Subject: [WATCHDOG] use ENOTTY instead of ENOIOCTLCMD in ioctl()
X-Git-Tag: firefly_0821_release~32540^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f311896a990a0b766e279defe9adff29160ada03;p=firefly-linux-kernel-4.4.55.git

[WATCHDOG] use ENOTTY instead of ENOIOCTLCMD in ioctl()

Return ENOTTY instead of ENOIOCTLCMD in user-visible ioctl() results

The watchdog drivers used to return ENOIOCTLCMD for bad ioctl() commands.
ENOIOCTLCMD should not be visible by the user, so use ENOTTY instead.
