Subject: [SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8163904e660a30be800a3361df69bf9dad3b44cd;p=openwrt%2Fstaging%2Fblogic.git

[SPARC]: Mark SBUS framebuffer ioctls as IGNORE in compat_ioctl.c

They are handled in a ->compat_ioctl() handler, so it's just noise
when compat_ioctl.c warns which occurs when they are used on non-SBUS
framebuffer devices.
