Subject: [PATCH 4.4 37/80] drivers: net: lmc: fix case value for target abort error

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

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

From: Colin Ian King <colin.king@...onical.com>

[ Upstream commit afb41bb039656f0cecb54eeb8b2e2088201295f5 ]

Current value for a target abort error is 0x010, however, this value
should in fact be 0x002.  As it stands, the range of error is 0..7 so
it is currently never being detected.  This bug has been in the driver
since the early 2.6.12 days (or before).

Detected by CoverityScan, CID#744290 ("Logically dead code")
