Hi Angel,

The code change looks fine. Here are a few patch style suggestions:

- If you do 'git log --oneline imx-media-utils.c' you'll see that
  changes in utils file only, seem to have utils in the patch subject
  prefix. "media: imx: utils:"

- Commit message is vague. How about being explicit so anyone persuing
  those one-liners knows exactly what change was made.
  "Enclose IMX_BUS_FMTS macro in parentheses"

- The commit log 'why' is to conform to the kernel coding style, not
  to fix a checkpatch error. It is good to say Issue found by
  checkpatch, but that itself is not the 'why'.
