staging:iio:impedance:ad5933: correct error check

2014-02-22T21:34:50+00:00

commit e9ed104de68c345c9a827225e93c74c6894613a9 upstream.

iio_kfifo_allocate returns NULL in case of error.

The semantic match that finds this problem is as follows:

*x = f(...);

staging: comedi: adv_pci1710: fix analog output readback value

2014-02-22T21:34:50+00:00

commit 1e85c1ea1ff2a60659e790ef8ec76c7339445841 upstream.

The last value written to a analog output channel is cached in the
private data of this driver for readback.

Currently, the wrong value is cached in the (*insn_write) functions.
The current code stores the data[n] value for readback afer the loop
has written all the values. At this time 'n' points past the end of
the data array.

Fix the functions by using a local variable to hold the data being
written to the analog output channel. This variable is then used
after the loop is complete to store the readback value. The current
value is retrieved before the loop in case no values are actually
written..

staging: r8188eu: Fix typo in USB_DEVICE list

2014-02-22T21:34:50+00:00

commit 08951f10ae146d0c4114ac508310ad316b6f8798 upstream.

There is a typo in the device list that interchanges the vendor and
product codes for one of the entries. This exchange was determined
by noticing that the vendor code is 0x07b8 for Abocom at
http://www.linux-usb.org/usb.ids.

staging: lustre: fix quotactl permission denied (LU-4530)

2014-02-22T21:34:49+00:00

commit 8b9e418c013e8b671fc10108ab14243f0657bffd upstream.

The changes introduced in commit 4b1a25f06b30b203 ("fix build when
CONFIG_UIDGID_STRICT_TYPE_CHECKS is on") got the UID check the wrong way
around, leading to "Permission denied" when a regular user attempts to
retrieve his quota (lfs quota -u ...) but allowing him to retrieve other
users quota.

zram: fix race between reset and flushing pending work

2014-02-06T19:34:06+00:00

commit da4a04126baa3be03bc566d4a2ee0944c5e783d0 upstream.

Dan and Sergey reported that there is a racy between reset and flushing
of pending work so that it could make oops by freeing zram->meta in
reset while zram_slot_free can access zram->meta if new request is
adding during the race window.

This patch moves flush after taking init_lock so it prevents new request
so that it closes the race.

commit 8f248dae133668bfb8e9379b4b3f0571c858b24a upstream.

byBBPreEDIndex value is initially 0, this means that from
cold BBvUpdatePreEDThreshold is never set.

This means that sensitivity may be in an ambiguous state,
failing to scan any wireless points or at least distant ones.
