[PATCH 4.16 06/31] mei: remove dev_err message on an unsupported ioctl

From: Greg Kroah-Hartman
Date: Fri Apr 06 2018 - 09:46:38 EST

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


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

commit bb0829a741792b56c908d7745bc0b2b540293bcc upstream.

Currently the driver spams the kernel log on unsupported ioctls which is
unnecessary as the ioctl returns -ENOIOCTLCMD to indicate this anyway.
I suspect this was originally for debugging purposes but it really is not
required so remove it.
