crypto: qat - fix mutex ordering in adf_rl

Browse source

[ Upstream commit 487caa8d5e ]

If the function validate_user_input() returns an error, the error path
attempts to unlock an unacquired mutex.
Acquire the mutex before calling validate_user_input(). This is not
strictly necessary but simplifies the code.
