Subject: [PATCH v5 15/18] compat_ioctl: ppp: move simple commands into ppp_generic.c
Date: Wed, 14 Aug 2019 20:54:50 +0000	[thread overview]
Message-ID: <20190814205521.122180-6-arnd@arndb.de> (raw)
In-Reply-To: <20190814204259.120942-1-arnd@arndb.de>

All ppp commands that are not already handled in ppp_compat_ioctl()
are compatible, so they can now handled by calling the native
ppp_ioctl() directly.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
