How do you think about a wording variant like the following?

Subject:
[PATCH v2] video/hdmi: Use “HDMI_VENDOR_INFOFRAME_SIZE” in hdmi_vendor_infoframe_init()

Change description:
Adjust the usage of a “magic” number here by adding a macro for
the vendor info frame size (similar to other video modules).

Markus
