For drivers which could have multiple instances, it is necessary to differentiate between which is which in the logs. Since DRM_INFO/WARN/ERROR don’t do this, drivers used dev_info/warn/err to make this differentiation. We now have DRM_DEV_* variants of the drm print macros, so we can start to convert those drivers back to using drm-formatted specific log messages. This patch is using following Coccinelle script: @@ @@ ( - dev_info + DRM_DEV_INFO | - dev_err + DRM_DEV_ERROR | - dev_dbg + DRM_DEV_DEBUG ) Signed-off-by: Aastha Gupta <aastha.gupta4104@xxxxxxxxx> --- drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c | 60 +++++++++++++++---------- 1 file changed, 37 insertions(+), 23 deletions(-) diff --git a/drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c b/drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c index 3cce3ca..42a9d4d 100644 --- a/drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c +++ b/drivers/gpu/drm/panel/panel-sharp-lq101r1sx01.c @@ -57,14 +57,14 @@ static int sharp_panel_write(struct sharp_panel *sharp, u16 offset, u8 value) err = mipi_dsi_generic_write(dsi, payload, sizeof(payload));
