drm/msm/hdmi: Drop redundant 'int' for longs

2026-03-25T06:06:09Z

'long' type is already an integer, so 'int' is redundant.

drm/msm/hdmi: Consistently use u32 instead of uint32_t

2026-03-25T06:06:09Z

Linux coding style asks to use kernel types like u32 instead of uint32_t and code already has it in other places, so unify the remaining pieces.

drm/msm/hdmi: Simplify with local 'dev' variable

2026-03-25T06:06:09Z

msm_hdmi_dev_probe() function already stores pdev->dev in local variable, so use it directly to make code simpler.

drm/msm/hdmi: Avoid double error print on msm_hdmi_get_phy() failure

2026-03-25T06:06:09Z

msm_hdmi_get_phy() already prints error messages on each error path using dev_err_probe(), so final DRM_DEV_ERROR() would duplicate it and possibly flood the dmesg on probe deferrals.

drm/msm/hdmi: Fix wrong CTRL1 register used in writing info frames

2026-03-25T06:06:09Z

Commit 384d2b03d0a1 ("drm/msm/hdmi: make use of the drm_connector_hdmi framework") changed the unconditional register writes in few places to updates: read, apply mask, write. The new code reads REG_HDMI_INFOFRAME_CTRL1 register, applies fields/mask for HDMI_INFOFRAME_CTRL0 register and finally writes to HDMI_INFOFRAME_CTRL0. This difference between CTRL1 and CTRL0 looks unintended and may result in wrong data being written to HDMI bridge registers.

drm/msm/hdmi: make 'msm_hdmi_pm_ops' static

2026-03-25T06:06:09Z

The struct 'msm_hdmi_pm_ops' is not used outside of the file it is defined in, so make it static. Fixes the following sparse warning: drivers/gpu/drm/msm/hdmi/hdmi.c:432:1: warning: symbol 'msm_hdmi_pm_ops' was not declared. Should it be static?

drm/msm: add missing MODULE_DEVICE_ID definitions

2026-03-25T06:06:03Z

The drm/msm module bundles several drivers, each of them having a separate OF match table, however only MDSS (subsystem), KMS devices and GPU have corresponding MODULE_DEVICE_ID tables. Add MODULE_DEVICE_ID to the display-related driver and to all other drivers in this module, simplifying userspace job.
