Subject: [PATCH] drm/etnaviv: NULL vs IS_ERR() buf in etnaviv_core_dump()
Date: Mon, 14 Jan 2019 10:49:46 +0000 [thread overview]
Message-ID: <20190114104946.GA22444@kadam> (raw)
The etnaviv_gem_get_pages() never returns NULL. It returns error
pointers on error.
Fixes: a8c21a5451d8 ("drm/etnaviv: add initial etnaviv DRM driver")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
