Subject: drm/gem-cma-helper: Change the level of the allocation failure message
Git-commit: e0ad7c0f37478853f12a723f46f87cd672ca9d67
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

drm_gem_cma_create() prints an error message when dma_alloc_wc() fails to
allocate the amount of memory we requested. This can lead to annoying
error messages when CMA is only one possible source of memory for the BO
allocation. Turn this error message into a debug one.
