Use dev_err_probe() to log errors in the probe function of all drm mediatek drivers. This avoids -EPROBE_DEFER return values from being logged as errors, like the following: mediatek-disp-rdma 1c002000.rdma: Failed to add component: -517 As a side benefit it also standardizes the format of the error in the log messages. Signed-off-by: Nícolas F. R. A. Prado <nfraprado@xxxxxxxxxxxxx> --- Changes in v2: - Converted all dev_err() in probe functions to dev_err_probe() instead of just the ones in the component_add() error path - Link to v1: https://lore.kernel.org/r/20240605-mtk-disp-rdma-dev-err-probe-v1-1-91259e1d3a93@xxxxxxxxxxxxx --- drivers/gpu/drm/mediatek/mtk_cec.c | 28 ++++++++-------------- drivers/gpu/drm/mediatek/mtk_disp_aal.c | 18 +++++++------- drivers/gpu/drm/mediatek/mtk_disp_ccorr.c | 18 +++++++------- drivers/gpu/drm/mediatek/mtk_disp_color.c | 18 +++++++------- drivers/gpu/drm/mediatek/mtk_disp_gamma.c | 18 +++++++------- drivers/gpu/drm/mediatek/mtk_disp_merge.c | 25 +++++++++----------- drivers/gpu/drm/mediatek/mtk_disp_ovl.c | 24 ++++++++----------- drivers/gpu/drm/mediatek/mtk_disp_ovl_adaptor.c | 4 ++-- drivers/gpu/drm/mediatek/mtk_disp_rdma.c | 31 +++++++++++-------------- drivers/gpu/drm/mediatek/mtk_dp.c | 8 +++---- drivers/gpu/drm/mediatek/mtk_ethdr.c | 19 +++++++-------- drivers/gpu/drm/mediatek/mtk_hdmi.c | 31 ++++++++++--------------- drivers/gpu/drm/mediatek/mtk_hdmi_ddc.c | 21 ++++++----------- drivers/gpu/drm/mediatek/mtk_mdp_rdma.c | 18 +++++++------- drivers/gpu/drm/mediatek/mtk_padding.c | 20 +++++++--------- 15 files changed, 125 insertions(+), 176 deletions(-) diff --git a/drivers/gpu/drm/mediatek/mtk_cec.c b/drivers/gpu/drm/mediatek/mtk_cec.c index 8519e9bade36..2de248443147 100644 --- a/drivers/gpu/drm/mediatek/mtk_cec.c +++ b/drivers/gpu/drm/mediatek/mtk_cec.c @@ -195,18 +195,14 @@ static int mtk_cec_probe(struct platform_device *pdev) spin_lock_init(&cec->lock);
