* USB: serial: fix module-license macrosJohan Hovold2017-11-041-1/+1
| | | | | | | | Several GPL-2.0 drivers used "GPL" rather than "GPL v2" in their MODULE_LICENSE macros; fix the macros to match the licenses. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman2017-11-041-0/+1
| | | | | | | | | | | | | | | | | | | | | It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

* USB: serial: make minor allocation dynamicGreg Kroah-Hartman2013-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | This moves the allocation of minor device numbers from a static array to be dynamic, using the idr interface. This means that you could potentially get "gaps" in a minor number range for a single USB serial device with multiple ports, but all should still work properly. We remove the 'minor' field from the usb_serial structure, as it no longer makes any sense for it (use the field in the usb_serial_port structure if you really want to know this number), and take the fact that we were overloading a number in this field to determine if we had initialized the minor numbers or not, and just use a flag variable instead. Note, we still have the limitation of 255 USB to serial devices in the system, as that is all we are registering with the TTY layer at this point in time.

| * TTY: switch tty_flip_buffer_pushJiri Slaby2013-01-151-20/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

* | USB: serial: fix null-pointer dereferences on disconnectJohan Hovold2013-02-131-11/+8
|/ | | | | | | | | | | | | | | | | | | | | Make sure serial-driver dtr_rts is called with disc_mutex held after checking the disconnected flag. Due to a bug in the tty layer, dtr_rts may get called after a device has been disconnected and the tty-device unregistered. Some drivers have had individual checks for disconnect to make sure the disconnected interface was not accessed, but this should really be handled in usb-serial core (at least until the long-standing tty-bug has been fixed). Note that the problem has been made more acute with commit 0998d0631001 ("device-core: Ensure drvdata = NULL when no driver is bound") as the port data is now also NULL when dtr_rts is called resulting in further oopses.

| | | | | | | | | | | | | | | This patch (as1551) cleans up the PM-related entries in the usb_driver structures of the various USB serial driver modules. Those entries are now filled in by the usb-serial core during driver registration, so they don't need to be initialized explicitly in the source code. The same is true of the one remaining no_dynamic_id entry. reset_resume remains a small problem, because the serial core doesn't support it. The patch ignores these entries.

* module_param: make bool parameters really bool (drivers & misc)Rusty Russell2012-01-131-1/+1
| | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

* tty: remove filp from the USB tty ioctlsAlan Cox2011-02-171-1/+1
| | | | | | | | We don't use it so we can trim it from here as we try and stamp the file object dependencies out of the serial code. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* tiocmget: kill off the passing of the struct fileAlan Cox2011-02-171-1/+1
| | | | | | | | | | We don't actually need this and it causes problems for internal use of this functionality. Currently there is a single use of the FILE * pointer. That is the serial core which uses it to check tty_hung_up_p. However if that is true then IO_ERROR is also already set so the check may be removed.

* USB: ssu100: remove max_packet_size calculationBill Pemberton2010-11-111-48/+8
| | | | | | | | The max_packet_size logic is taken from ftdi_sio, but it's not needed for this device. This also makes proces_read_urb simpler. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | Simple pasting job using the new ops function. Also fix a couple of devices directly returning the internal struct (which happens at this point to match for the fields that matter but isn't correct or futureproof) Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
