libata: fix unexpectedly frozen port after ata_eh_reset()

2011-08-03T19:42:43+00:00

commit 8c56cacc724c7650b893d43068fa66044aa29a61 upstream.

To work around controllers which can't properly plug events while
reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING
after reset but before RESET is marked done.  As reset is the final
recovery action and full verification of devices including onlineness
and classfication match is done afterwards, this shouldn't lead to
lost devices or missed hotplug events.

Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so
if the condition happens after resetting an empty port, the port could
be left frozen and EH will end without thawing it, making the port
unresponsive to further hotplug events.

Thaw if the port is frozen after clearing EH_PENDING.  This problem is
reported by Bruce Stenning in the following thread.

stable: I think we should weather this patch a bit longer in -rcX
	before sending it to -stable.  Please wait at least a month
	after this patch makes upstream.  Thanks.

-v2: Fixed spelling in the comment per Dave Howorth.

mmc: sdhci-esdhc-imx: SDHCI_CARD_PRESENT does not get cleared

2011-08-03T19:42:42+00:00

commit 803862a6f7de4939e0a557214e5e4b37e36f87ff upstream.

The function esdhc_readl_le intends to clear bit SDHCI_CARD_PRESENT,
when the card detect gpio tells there is no card.  But it does not
clear the bit actually.  The patch gives a fix on that.

mmc: Added quirks for Ricoh 1180:e823 lower base clock frequency

2011-08-03T19:42:42+00:00

commit 15bed0f2fa8e1d7db201692532c210a7823d2d21 upstream.

Ricoh 1180:e823 does not recognize certain types of SD/MMC cards,
as reported at http://launchpad.net/bugs/773524.  Lowering the SD
base clock frequency from 200Mhz to 50Mhz fixes this issue. This
solution was suggest by Koji Matsumuro, Ricoh Company, Ltd.

This change has no negative performance effect on standard SD
cards, though it's quite possible that there will be one on
UHS-1 cards.

hwmon: (max1111) Fix race condition causing NULL pointer exception

commit d3f684f2820a7f42acef68bea6622d9032127fb2 upstream.

spi_sync call uses its spi_message parameter to keep completion information,
using a drvdata structure is not thread-safe. Use a mutex to prevent
multiple access to shared driver data.

hwmon: (it87) Fix label group removal

2011-08-03T19:42:40+00:00

commit fa8b69758e65b406c8010936b541cd00deef804d upstream.

A copy-and-paste error caused it87_attributes_vid to be referenced
where it87_attributes_label should be. Thankfully the group is only
used for attribute removal, not attribute creation, so the effects of
this bug are limited, but let's fix it still.

Revert "V4L/DVB: cx23885: Enable Message Signaled Interrupts(MSI)"

2011-08-03T19:42:38+00:00

commit d7515b8866b60c9526d2d7af37ebcd16c3c5ed97 upstream.

This reverts commit e38030f3ff02684eb9e25e983a03ad318a10a2ea.

MSI flat-out doesn't work right on cx2388x devices yet. There are now
multiple reports of cards that hard-lock systems when MSI is enabled,
including my own HVR-1250 when trying to use its built-in IR receiver.
Disable MSI and it works just fine. Similar for another user's HVR-1270.
Issues have also been reported with the HVR-1850 when MSI is enabled,
and the 1850 behavior sounds similar to an as-yet-undiagnosed issue I've
seen with an 1800.

drm/radeon: fix oops in ttm reserve when pageflipping (v2)

commit 498c555f56a02ec1059bc150cde84411ba0ac010 upstream.

We need to take a reference to this object, pinning doesn't take a reference
so if userspace deletes the object it can disappear even if pinned.

v2: fix error paths to unreference properly also.
