From: Alexey Khoroshilov <khoroshilov@xxxxxxxxx>
commit b833d0df943d70682e288c38c96b8e7bfff4023a upstream.
Commit af8a819a2513 ("[media] lirc_imon: simplify error handling code")
lost mutex_unlock(&context->ctx_lock), so imon_probe() exits with
the context->ctx_lock mutex acquired.
The patch adds mutex_unlock(&context->ctx_lock) back.
Found by Linux Driver Verification project (linuxtesting.org).
Fixes: af8a819a2513 ("[media] lirc_imon: simplify error handling code")
