* sisusb: remove dummy variablesJiri Slaby2016-06-251-15/+13
| | | | | | | | | | | bytes_written parameter of sisusb_copy_memory and sisusb_read_memory is an out parameter, but its value is never used.

* usb-misc: sisusbvga: fix error pathPeter Senna Tschudin2016-01-241-1/+2
| | | | | | | | | | | Remove a call to dev_err() that was reporting an unsuccesful call to kmalloc(), as reporting memory allocation failures is redundant. Instead of logging the error, clean up previously allocated resources and abort the probe with -ENOMEM. Before this change sisusb->SiS_Pr could be dereferenced even if null after failure of memory allocation.

| | | | | | | | | | | | | | | | | This patch remove three calls to dev_err() from sisusb_probe() as reporting memory allocation failures is redundant: - Remove a call to dev_err() that was reporting unsuccesful call to kzalloc(). - Remove two calls to dev_err() that were reporting unsuccesful calls to kmalloc(). One call to dev_err() reporting memory allocation is left unchanged as the last patch of the series removes it.

| | | | | | | | | | | | | | | | This patch falls out of my work to fix usbmon so it uses virtual addresses. It is not necessary, the "new" usbmon should work just fine with sisusbvga. However, it seems ridiculous that anyone would use uncached memory to transfer bulk data. Dropping the unnecessary use of usb_buffer_alloc should be beneficial here, in case anyone ever uses the dongle on anything beyond x86. I had no success in raising the author of the driver by e-mail, so the patch is not actually tested.

* USB: prevent char device open/deregister raceAlan Stern2007-07-121-33/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as908) adds central protection in usbcore for the prototypical race between opening and unregistering a char device. The spinlock used to protect the minor-numbers array is replaced with an rwsem, which can remain locked across a call to a driver's open() method. This guarantees that open() and deregister() will be mutually exclusive. The private locks currently used in several individual drivers for this purpose are no longer necessary, and the patch removes them. The following USB drivers are affected: usblcd, idmouse, auerswald, legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and usb-skeleton. As a side effect of this change, usb_deregister_dev() must not be called while holding a lock that is acquired by open(). Unfortunately a number of drivers do this, but luckily the solution is simple: call usb_deregister_dev() before acquiring the lock. In addition to these changes (and their consequent code simplifications), the patch fixes a use-after-free bug in adutux and a race between open() and release() in iowarrior.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

| | | | | | | | | | | | | | This patch contains the following possible cleanups: - make needlessly global functions static - function and struct declarations belong into header files - make SiS_VCLKData const - #if 0 the following unused global functions: - sisusb.c: sisusb_writew() - sisusb.c: sisusb_readw() - sisusb_init.c: SiSUSB_GetModeID() Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] USB: convert the semaphores in the sisusb driver to mutexesArjan van de Ven2006-06-211-38/+39
| | | | | | | | | | | | | From: Arjan van de Ven <arjan@infradead.org> Convert the semaphores-used-as-mutex to mutexes in the sisusb video driver; this required manual checking due to the "return as locked" stuff in this driver, but the ->lock semaphore is still used as mutex in the end.

* [PATCH] USB: mark various usb tables constArjan van de Ven2006-01-041-2/+2
| | | | | | | | | | patch below marks various USB tables and variables as const so that they end up in .rodata section and don't cacheline share with things that get written to. For the non-array variables it also allows gcc to optimize more. Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
