usb: Add export.h for EXPORT_SYMBOL/THIS_MODULE where needed

2011-10-31T23:31:25+00:00

With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.

Use the lightweight version of the header that has just THIS_MODULE
and EXPORT_SYMBOL variants.

usb: Add module.h to drivers/usb consumers who really use it.

2011-10-31T23:31:25+00:00

The situation up to this point meant that module.h was pretty
much everywhere, regardless of whether you asked for it or not.
We are fixing that, so give the USB folks who want it an actual
include of it.

USB: Realtek cr: Fix driver freeze issue

2011-09-18T08:51:34+00:00

After auto-delink command is triggered, the CSW won't be sent back
to host side, in which scenario, the USB Mass Storage driver will
wait for the completion of the URB for MAX_SCHEDULE_TIMEOUT.

Merge branch 'master' into for-next

2011-09-15T13:08:18+00:00

Fast-forward merge with Linus to be able to merge patches
based on more recent version of the tree.

Remove unneeded version.h includes (and add where needed) for drivers/usb/

2011-09-15T12:57:07+00:00

It was pointed out by 'make versioncheck' that linux/version.h was not
always being included where needed and sometimes included needlessly
in drivers/usb/.
This patch fixes up the includes.

For the UVC gadget driver bits, this was ACK'ed by Laurent Pinchart.

USB: storage: Use normalized sense when emulating autosense

2011-09-09T22:55:03+00:00

This patch solves two things:
1) Enables autosense emulation code to correctly
interpret descriptor format sense data, and
2) Fixes a bug whereby the autosense emulation
code would overwrite descriptor format sense data
with SENSE KEY HARDWARE ERROR in fixed format, to
incorrectly look like this:

Oct 21 14:11:07 localhost kernel: sd 7:0:0:0: [sdc]  Sense Key : Recovered Error [current] [descriptor]
Oct 21 14:11:07 localhost kernel: Descriptor sense data with sense descriptors (in hex):

ums_realtek: do not use stack memory for DMA

2011-08-24T22:06:54+00:00

This patch changes rts51x_read_mem, rts51x_write_mem, and rts51x_read_status to
allocate temporary buffers with kmalloc. This way stack addresses are not used
for DMA when these functions call rts51x_bulk_transport.

usb_storage: Don't freeze in usb-stor-scan

2011-08-22T22:21:15+00:00

Scanning cannot be run during suspend or hibernation, but if
usb-stor-scan freezes another thread waiting on scanning to
complete may fail to freeze.

However, if usb-stor-scan is left freezable without ever actually
freezing then the freezer will wait on it to exit, and threads
waiting for scanning to finish will no longer be blocked. One
problem with this approach is that usb-stor-scan has a delay to
wait for devices to settle (which is currently the only point where
it can freeze). To work around this we can request that the freezer
send a fake signal when freezing, then use interruptible sleep to
wake the thread early when freezing happens.

To make this happen, the following changes are made to
usb-stor-scan:

 * Use set_freezable_with_signal() instead of set_freezable() to
   request a fake signal when freezing

 * Use wait_event_interruptible_timeout() instead of
   wait_event_freezable_timeout() to avoid freezing
