Subject: mei: remove dev_err message on an unsupported ioctl
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bb0829a741792b56c908d7745bc0b2b540293bcc;p=linux.git

mei: remove dev_err message on an unsupported ioctl

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.
