Subject: [PATCH] drm/ttm: add __user annotation in radeon_ttm_vram_read
Date: Sat, 24 Oct 2020 02:47:06 +0200	[thread overview]
Message-ID: <20201024004706.24518-1-linux@rasmusvillemoes.dk> (raw)

Keep sparse happy by preserving the __user annotation when casting.

Reported-by: kernel test robot <lkp@intel.com>
Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk>

kernel test robot has already started spamming me due to 9c5743dff. If
I don't fix those warnings I'll keep getting those emails for
months, so let me do the easy ones.
