Re: [PATCH v4 2/4] drm/edid: parse HDMI 2.1 gaming (ALLM/VRR) capabilities from HF-VSDB

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] Kerneldoc comments for `struct drm_hdmi_vrr_cap` refer to non-existent fields `@mcnmvrr` and `@mcinema_vrr` instead of `cnmvrr` and `cinema_vrr`, and contain minor typos.

drm/edid: parse HDMI 2.1 gaming (ALLM/VRR) capabilities from HF-VSDB

This commit parses the HDMI 2.1 gaming-related capabilities from the HDMI
Forum VSDB (HF-VSDB). It exposes them through struct drm_hdmi_info and
adds a new struct drm_hdmi_vrr_cap to describe VRR capabilities.

[Severity: Low]
This isn't a bug, but there is a typo here ("fom" instead of "from").

[Severity: Low]
This isn't a bug, but does this kerneldoc mismatch the field name? 
The documentation uses @mcnmvrr while the field is named cnmvrr.

[Severity: Low]
This isn't a bug, but similarly here, the kerneldoc uses @mcinema_vrr 
instead of cinema_vrr.

[Severity: Low]
This isn't a bug, but there is a typo here ("inide" instead of "inside").
