Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-nextdrm-next-2018-12-27
Lucas writes: "nothing major this time, mostly some cleanups that were found on the way of reworking the code in preparation for new feature additions." Small conflict in drivers/gpu/drm/etnaviv/etnaviv_drv.c because drm-misc-next also has a patch to switch over to _put() functions. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> From: Lucas Stach <l.stach@pengutronix.de> Link: https://patchwork.freedesktop.org/patch/msgid/1545130845.5874.23.camel@pengutronix.de
