From 407e9ef72476e64937ebec44cc835e03a25fb408 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 11 Sep 2018 17:23:00 +0200 Subject: compat_ioctl: move drivers to compat_ptr_ioctl 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. Acked-by: Greg Kroah-Hartman Acked-by: Michael S. Tsirkin Acked-by: David S.
