Subject: [PATCH 1/2] drm/qxl: don't touch mem.bus.offset
Date: Mon,  7 Sep 2020 15:29:32 +0200	[thread overview]
Message-ID: <20200907132933.5401-1-christian.koenig@amd.com> (raw)

This is internal to TTM and should not be used by drivers directly.

Drop the call to qxl_ttm_io_mem_reserve() and use mem->start instead.
