dm ioctl: only issue uevent on resume if state changed

2010-03-15T16:07:08+00:00

commit 0f3649a9e305ea22eb196a84a2d7520afcaa6060 upstream.

Only issue a uevent on a resume if the state of the device changed,
i.e. if it was suspended and/or its table was replaced.

dm: free dm_io before bio_endio not after

2010-03-15T16:07:08+00:00

commit a97f925a32aad2a37971d7bfb657006acf04e42d upstream.

Free the dm_io structure before calling bio_endio() instead of after it,
to ensure that the io_pool containing it is not referenced after it is
freed.

This partially fixes a problem described here
  https://www.redhat.com/archives/dm-devel/2010-February/msg00109.html

thread 1:
bio_endio(bio, io_error);
/* scheduling happens */
					thread 2:
					close the device
					remove the device
thread 1:
free_io(md, io);

Thread 2, when removing the device, sees non-empty md->io_pool (because the
io hasn't been freed by thread 1 yet) and may crash with BUG in mempool_free.
Thread 1 may also crash, when freeing into a nonexisting mempool.

To fix this we must make sure that bio_endio() is the last call and
the md structure is not accessed afterwards.

There is another bio_endio in process_barrier, but it is called from the thread
and the thread is destroyed prior to freeing the mempools, so this call is
not affected by the bug.

A similar bug exists with module unloads - the module may be unloaded
immediately after bio_endio - but that is more difficult to fix.

rtc-coh901331: fix braces in resume code

2010-03-15T16:07:05+00:00

commit 5a98c04d78c896d52baef20ffc11f6d1ba6eb786 upstream.

The else part of the if statement is indented but does not have braces
around it. It clearly should since it uses clk_enable and clk_disable
which are supposed to balance.

s3cmci: initialize default platform data no_wprotect and no_detect with 1

2010-03-15T16:07:04+00:00

commit c212808a1ba6bfba489006399b8152a047305acf upstream.

If no platform_data was givin to the device it's going to use it's default
platform data struct which has all fields initialized to zero.  As a
result the driver is going to try to request gpio0 both as write protect
and card detect pin.  Which of course will fail and makes the driver
unusable

Previously to the introduction of no_wprotect and no_detect the behavior
was to assume that if no platform data was given there is no write protect
or card detect pin.  This patch restores that behavior.

drm/i915: Use a dmi quirk to skip a broken SDVO TV output.

2010-03-15T16:07:00+00:00

commit 6070a4a928f8c92b9fae7d6717ebbb05f425d6b2 upstream.

This IBM system has a multi-function SDVO card that reports both VGA
and TV, but the system has no TV connector.  The TV connector always
reported as connected, which would lead to poor modesetting choices.

USB: unusual_devs: Add support for multiple Option 3G sticks

2010-03-15T16:06:59+00:00

commit 46216e4fbe8c62059b5440dec0b236f386248a41 upstream.

Enable the SD-Card interface on multiple Option 3G sticks.
The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an interface
driver.
