[PATCH 3.18 78/93] mei: remove dev_err message on an unsupported ioctl
From: Greg Kroah-Hartman
Date: Fri Apr 06 2018 - 09:28:22 EST
3.18-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.
