Subject: drm/nouveau/kms/nv04-nv4x: Use match_string() helper to simplify the code
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2574c809d7c0f07f11fdefd9894e51e126ee1d66;p=linux.git

drm/nouveau/kms/nv04-nv4x: Use match_string() helper to simplify the code

match_string() returns the array index of a matching string.
Use it instead of the open-coded implementation.
