mei: bus: fix received data size check in NFC fixup
commit 582ab27a063a506ccb55fc48afcc325342a2deba upstream.
NFC version reply size checked against only header size, not against
full message size. That may lead potentially to uninitialized memory access
in version data.
That leads to warnings when version data is accessed:
drivers/misc/mei/bus-fixup.c: warning: '*((void *)&ver+11)' may be used uninitialized in this function [-Wuninitialized]: => 212:2
Reported in
Build regressions/improvements in v4.9-rc3
https://lkml.org/lkml/2016/10/30/57
[js] the check is in 3.12 only once
Fixes: 59fcd7c63abf (mei: nfc: Initial nfc implementation)
