[ 1/3] btrfs: dont stop searching after encountering the wrong item

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gabriel de Perthuis <g2p.code@gmail.com>

commit 03b71c6ca6286625d8f1ed44aabab9b5bf5dac10 upstream.

The search ioctl skips items that are too large for a result buffer, but
inline items of a certain size occuring before any search result is
found would trigger an overflow and stop the search entirely.

[ 2/3] hwmon: fix error return code in abituguru_probe()

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

commit ecacb0b17c08fae89f65468727f0e4b8e91da4e1 upstream.

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

[ 3/3] media: mantis: fix silly crash case

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alan Cox <alan@linux.intel.com>

commit e1d45ae10aea8e8a403e5d96bf5902ee670007ff upstream.

If we set mantis->fe to NULL on an error its not a good idea to then try
passing NULL to the unregister paths and oopsing really.

This kernel can be built and boot without any problem.
Building a kernel with this kernel also works fine.

 - Build Machine: debian wheezy x86_64
   CPU: Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz x 4
   memory: 8GB

 - Test machine: debian wheezy x86_64(KVM guest on the Build Machine)
   vCPU: x2
   memory: 2GB

Thanks,
Satoru
