Subject: [PATCH v3 09/26] compat_ioctl: move drivers to compat_ptr_ioctl
Date: Tue, 16 Apr 2019 22:19:47 +0200 [thread overview]
Message-ID: <20190416202013.4034148-10-arnd@arndb.de> (raw)
In-Reply-To: <20190416202013.4034148-1-arnd@arndb.de>
Each of these drivers has a copy of the same trivial helper function to
convert the pointer argument and then call the native ioctl handler.
We now have a generic implementation of that, so use it.
