xhci: Remove scary warnings about transfer issues.

2012-12-06T11:20:19Z

commit 2a9227a5eeaeb3f91e3a72ceea4fa59016ca5d20 upstream. Getting a short packet or a babble error is usually a recoverable error, so stop scaring users with warnings in dmesg when xHCI debugging is turned off. Signed-off-by: Sarah Sharp Signed-off-by: Ben Hutchings

xhci: Remove warnings about MSI and MSI-X capabilities.

2012-12-06T11:20:19Z

commit 3b9783b277e66731891ab42eeaacebbdcdd6e629 upstream. xHCI host controllers may not be capable of MSI, but they should be able to be used in legacy PCI interrupt mode. Similarly, some xHCI host controllers will have MSI support but not MSI-X support. Lower the dmesg log level from an error to debug. The message won't appear unless CONFIG_USB_XHCI_HCD_DEBUGGING is turned on. If we need to find out whether the device can support MSI or MSI-X and it's not being enabled by the driver, it's easy to ask the user to run lspci.

usb: use usb_serial_put in usb_serial_probe errors

2012-12-06T11:20:13Z

commit 0658a3366db7e27fa32c12e886230bb58c414c92 upstream. The use of kfree(serial) in error cases of usb_serial_probe was invalid - usb_serial structure allocated in create_serial() gets reference of usb_device that needs to be put, so we need to use usb_serial_put() instead of simple kfree().

USB: mos7840: remove unused variable

2012-11-16T16:46:51Z

Fix warning about unused variable introduced by commit e681b66f2e19fa ("USB: mos7840: remove invalid disconnect handling") upstream. A subsequent fix which removed the disconnect function got rid of the warning but that one was only backported to v3.6.

xhci: Fix potential NULL ptr deref in command cancellation.

2012-10-30T23:27:05Z

commit 43a09f7fb01fa1e091416a2aa49b6c666458c1ee upstream. The command cancellation code doesn't check whether find_trb_seg() couldn't find the segment that contains the TRB to be canceled. This could cause a NULL pointer deference later in the function when next_trb is called. It's unlikely to happen unless something is wrong with the command ring pointers, so add some debugging in case it happens. This patch should be backported to stable kernels as old as 3.0, that contain the commit b63f4053cc8aa22a98e3f9a97845afe6c15d0a0d "xHCI: handle command after aborting the command ring".

2012-10-30T23:27:04Z
