From 67a6680d64e18c7a1901f31ef747ea53b6cd986d Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>

Subject: [PATCH] [PATCH] fbdev: Sanitize ->fb_ioctl prototype

The ioctl and file arguments to ->fb_mmap are totally unused and there's not
reason a driver should need them.

Also update the ->fb_compat_ioctl prototype to be the same as ->fb_mmap.
