Subject: ipc: lost unlock and fput in mqueue.c on error path
X-Git-Tag: MMI-PSA29.97-13-9~38220
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fd79b77117f16264206ed2618199d42e93cc8f09;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

ipc: lost unlock and fput in mqueue.c on error path

The error path in sys_mq_getsetattr() after the call to
audit_mq_getsetattr() is wrong - the info->lock is not unlocked and the
struct file *filp is not put.

Fix them both.
