This results in DTM warnings when hdcp is not even being enabled. This spams the dmesg and doesn't effect normal display functionality so it is better to log it using DRM_DEBUG_KMS() [How] Change the DRM_WARN() to DRM_DEBUG_KMS() Signed-off-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@xxxxxxx> Acked-by: Alex Deucher <alexander.deucher@xxxxxxx> Reviewed-by: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/gpu/drm/amd/display/modules/hdcp/hdcp_log.h b/drivers/gpu/drm/amd/display/modules/hdcp/hdcp_log.h index d3192b9d0c3d8..47f8ee2832ff0 100644 --- a/drivers/gpu/drm/amd/display/modules/hdcp/hdcp_log.h +++ b/drivers/gpu/drm/amd/display/modules/hdcp/hdcp_log.h @@ -27,7 +27,7 @@ #define MOD_HDCP_LOG_H_ #ifdef CONFIG_DRM_AMD_DC_HDCP -#define HDCP_LOG_ERR(hdcp, ...)
