commit c9d09dc7ad106492c17c587b6eeb99fe3f43e522 upstream.

Without this change, the USB cable for Freestyle Option and compatible
glucometers will not be detected by the driver.

serial: vt8500: add missing braces

2013-11-04T12:35:21+00:00

commit d969de8d83401683420638c8107dcfedb2146f37 upstream.

Due to missing braces on an if statement, in presence of a device_node a
port was always assigned -1, regardless of any alias entries in the
device tree. Conversely, if device_node was NULL, an unitialized port
ended up being used.

This patch adds the missing braces, fixing the issues.

wireless: cw1200: acquire hwbus lock around cw1200_irq_handler() call.

2013-11-04T12:35:21+00:00

commit 4978705d26149a629b9f50ff221caed6f1ae3048 upstream.

This fixes "lost interrupt" problems that occurred on SPI-based systems.
cw1200_irq_handler() expects the hwbus to be locked, but on the
SPI-path, that lock wasn't taken (unlike in the SDIO-path, where the
generic SDIO-code takes care of acquiring the lock).

w1 - call request_module with w1 master mutex unlocked

2013-11-04T12:35:20+00:00

commit bc04d76d6942068f75c10790072280b847ec6f1f upstream.

request_module for w1 slave modules needs to be called with the w1
master mutex unlocked. Because w1_attach_slave_device gets always(?)
called with mutex locked, we need to temporarily unlock the w1 master
mutex for the loading of the w1 slave module.

dm snapshot: fix data corruption

2013-11-04T12:35:19+00:00

commit e9c6a182649f4259db704ae15a91ac820e63b0ca upstream.

This patch fixes a particular type of data corruption that has been
encountered when loading a snapshot's metadata from disk.

When we allocate a new chunk in persistent_prepare, we increment
ps->next_free and we make sure that it doesn't point to a metadata area
by further incrementing it if necessary.

When we load metadata from disk on device activation, ps->next_free is
positioned after the last used data chunk. However, if this last used
data chunk is followed by a metadata area, ps->next_free is positioned
erroneously to the metadata area. A newly-allocated chunk is placed at
the same location as the metadata area, resulting in data or metadata
corruption.

This patch changes the code so that ps->next_free skips the metadata
area when metadata are loaded in function read_exceptions.

The patch also moves a piece of code from persistent_prepare_exception
to a separate function skip_metadata to avoid code duplication.

gpio/lynxpoint: check if the interrupt is enabled in IRQ handler

2013-11-04T12:35:19+00:00

commit 03d152d5582abc8a1c19cb107164c3724bbd4be4 upstream.

Checking LP_INT_STAT is not enough in the interrupt handler because its
contents get updated regardless of whether the pin has interrupt enabled or
not. This causes the driver to loop forever for GPIOs that are pulled up.

Fix this by checking the interrupt enable bit for the pin as well.

davinci_emac.c: Fix IFF_ALLMULTI setup

2013-11-04T12:35:18+00:00

[ Upstream commit d69e0f7ea95fef8059251325a79c004bac01f018 ]

When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't,
emac_dev_mcast_set should only enable RX of multicasts and reset
MACHASH registers.

It does this, but afterwards it either sets up multicast MACs
filtering or disables RX of multicasts and resets MACHASH registers
again, rendering IFF_ALLMULTI flag useless.

This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and
disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set.

Tested with kernel 2.6.37.
