Subject: [PATCH] drm/tinydrm: Replace dev_error with DRM_DEV_ERROR

Convert instances of dev_error to DRM_DEV_ERROR as we have
DRM_DEV_ERROR variants of drm print macros.

Please fix these alignment issues, or maybe just put it all on one line:

CHECK: Alignment should match open parenthesis
#59: FILE: drivers/gpu/drm/tinydrm/repaper.c:477:
+               DRM_DEV_ERROR(&epd->spi->dev, "Failed to get temperature
(%d)\n",
                        ret);

CHECK: Alignment should match open parenthesis
#152: FILE: drivers/gpu/drm/tinydrm/repaper.c:995:
+                       DRM_DEV_ERROR(dev, "Failed to get thermal zone:
%s\n",
                                thermal_zone);

With that changed you can add to your next version:
