drm/radeon: fix load detect on rn50 with hardcoded EDIDs.

2012-04-22T22:39:18+00:00

commit a09d431f344d854e4fe9cfac44f78cb8202f3eb7 upstream.

When the force changes went in back in 3.3.0, we ended up returning
disconnected in the !force case, and the connected in when forced,
as it hit the hardcoded check.

Fix it so all exits go via the hardcoded check and stop spurious
modesets on platforms with hardcoded EDIDs.

drm/radeon: disable MSI on RV515

2012-04-22T22:39:18+00:00

commit 16a5e32b83fd946312b9b13590c75d20c95c5202 upstream.

My rv515 card is very flaky with msi enabled. Every so often it loses a rearm
and never comes back, manually banging the rearm brings it back.

drm/radeon/kms: fix the regression of DVI connector check

2012-04-22T22:39:18+00:00

commit e36325071832f1ba96ac54fb8ba1459f08b05dd8 upstream.

The check of the encoder type in the commit [e00e8b5e: drm/radeon/kms:
fix analog load detection on DVI-I connectors] is obviously wrong, and
it's the culprit of the regression on my workstation with DVI-analog
connection resulting in the blank output.

Fixed the typo now.

drm/i915: Hold mode_config lock whilst changing mode for lastclose()

2012-04-22T22:39:18+00:00

commit c291be9dba370ba696a0d482249a212cf5c15f45 upstream.

Upon lastclose(), we switch back to the fbcon configuration. This
requires taking the mode_config lock in order to serialise the change
with output probing elsewhere.

Bluetooth: Adding USB device 13d3:3375 as an Atheros AR3012.

commit 9498ba7a1d38d42eef4ef6d906ab1743c9f0fd6f upstream.

The bluetooth module in the Asus UX31/UX21 is based on Atheros AR3012
and requires a firmware to be uploaded before it's usable.

spi-topcliff-pch: fix -Wuninitialized warning

2012-04-22T22:39:17+00:00

commit de3bd7e6de25141c466773c2e0fa319b2fa93655 upstream.

Fix for:
drivers/spi/spi-topcliff-pch.c: In function ‘pch_spi_handler_sub’:
drivers/spi/spi-topcliff-pch.c:325:17: warning: ‘bpw_len’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘rx_index’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘tx_index’ may be
  used uninitialized in this function [-Wuninitialized]

Move usage of tx_index, rx_index and bpw_len into the same
block as where they are set to prevent uninitialized usage.

v2: instead of init variables with 0 move the whole block

[This patch title "warnings" makes you think "This patch is not
for bug fix".  However, this patch surely patch for bug fix.]

usb: gadget: pch_udc: Reduce redundant interrupt

2012-04-22T22:39:17+00:00

commit 833310402c54ad9b676b465fc53ad276b13d36be upstream.

ISSUE:
USB Suspend interrupts occur frequently.

CAUSE:
When it is called pch_udc_reconnect() in USB Suspend, it repeats reset and
Suspend.

SOLUTION:
pch_udc_reconnect() does not enable all interrupts.  When an enumeration event
occurred the driver enables all interrupts.

usb: gadget: pch_udc: Fix usb/gadget/pch_udc: Fix ether gadget connect/disconnect issue

commit 1c575d2d2e3ff2a7cb3c2e2165064199cfd8ad32 upstream.

ISSUE:
After a USB cable is connect/disconnected, the system rarely freezes.

CAUSE:
Since the USB device controller cannot know to disconnect the USB cable, when
it is used without detecting VBUS by GPIO, the UDC driver does not notify to
USB Gadget.

Since USB Gadget cannot know to disconnect, a false setting occurred when the
USB cable is connected/disconnect repeatedly.
