| * ARM: pxa: fix error handling in pxa2xx_drv_pcmcia_probeAxel Lin2012-02-161-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | If pxa2xx_drv_pcmcia_add_one fails, it will go to err1 error path. Add a missing clk_put in the error path. Checking the ret value after the for loop is redundant, it is always false. Thus remove the redundant checking.

A fatal oops quickly follows this warning - often even just a 'dmesg' following the warning causes the kernel to oops. While testing suspend/resume on an ARM device with PCMCIA support, and a CF card inserted, I found that after five suspend and resumes, the kernel would complain, and shortly die after with slab corruption. WARNING: at include/linux/kref.h:41 kobject_get+0x28/0x50() As the message doesn't give a clue about which kobject, and the built-in debugging in drivers/base/power/main.c happens too late, this was added right before each get_device(): printk("%s: %p [%s] %u\n", __func__, dev, kobject_name(&dev->kobj), atomic_read(&dev->kobj.kref.refcount)); and on the 3rd s2ram cycle, the following behaviour observed: On the 3rd suspend/resume cycle: dpm_prepare: c1a0d998 [pcmcia_socket0] 3 dpm_suspend: c1a0d998 [pcmcia_socket0] 3 dpm_suspend_noirq: c1a0d998 [pcmcia_socket0] 3 dpm_resume_noirq: c1a0d998 [pcmcia_socket0] 3 dpm_resume: c1a0d998 [pcmcia_socket0] 3 dpm_complete: c1a0d998 [pcmcia_socket0] 2 4th: dpm_prepare: c1a0d998 [pcmcia_socket0] 2 dpm_suspend: c1a0d998 [pcmcia_socket0] 2 dpm_suspend_noirq: c1a0d998 [pcmcia_socket0] 2 dpm_resume_noirq: c1a0d998 [pcmcia_socket0] 2 dpm_resume: c1a0d998 [pcmcia_socket0] 2 dpm_complete: c1a0d998 [pcmcia_socket0] 1 5th: dpm_prepare: c1a0d998 [pcmcia_socket0] 1 dpm_suspend: c1a0d998 [pcmcia_socket0] 1 dpm_suspend_noirq: c1a0d998 [pcmcia_socket0] 1 dpm_resume_noirq: c1a0d998 [pcmcia_socket0] 1 dpm_resume: c1a0d998 [pcmcia_socket0] 1 dpm_complete: c1a0d998 [pcmcia_socket0] 0 ------------[ cut here ]------------ WARNING: at include/linux/kref.h:41 kobject_get+0x28/0x50() Modules linked in: ucb1x00_core Backtrace: [<c0212090>] (dump_backtrace+0x0/0x110) from [<c04799dc>] (dump_stack+0x18/0x1c) [<c04799c4>] (dump_stack+0x0/0x1c) from [<c021cba0>] (warn_slowpath_common+0x50/0x68) [<c021cb50>] (warn_slowpath_common+0x0/0x68) from [<c021cbdc>] (warn_slowpath_null+0x24/0x28) [<c021cbb8>] (warn_slowpath_null+0x0/0x28) from [<c0335374>] (kobject_get+0x28/0x50) [<c033534c>] (kobject_get+0x0/0x50) from [<c03804f4>] (get_device+0x1c/0x24) [<c0388c90>] (dpm_complete+0x0/0x1a0) from [<c0389cc0>] (dpm_resume_end+0x1c/0x20) ...

* | USB/PCI/PCMCIA: Clean up new_id and remove_id sysfs attribute routinesAlan Stern2012-01-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1514) cleans up some places where new_id and remove_id sysfs attributes are created and deleted. Handling both attributes in a single routine rather than a pair of routines makes the code smaller. It also prevents certain kinds of errors, like one we currently have in the USB subsystem: The removeid attribute is often created even when newid isn't (because the driver's no_dynamid_id flag is set). In the case of the PCMCIA subsystem, the newid attribute is created but never explicitly deleted. The patch adds a deletion routine.

* | Dynamic ID addition doesn't need get_driver()Alan Stern2012-01-241-4/+1
|/ | | | | | | | | | | | | | | | | | | | | As part of the removal of get_driver()/put_driver(), this patch (as1511) changes all the places that add dynamic IDs for drivers. Since these additions are done by writing to the drivers' sysfs attribute files, and the attributes are removed when the drivers are unregistered, there is no reason to take an extra reference to the drivers. The one exception is the pci-stub driver, which calls pci_add_dynid() as part of its registration. But again, there's no reason to take an extra reference here, because the driver can't be unloaded while it is being registered.

As this header is scheduled for cleanup (and elimination) keeping the status quo will cause build errors. So lets fix properly and independent of the future work.
