Subject: drm: fix typo in edid vendor parsing.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=16456c872e4e3d674dde73f9bdf3f69c0d95e070;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm: fix typo in edid vendor parsing.

Should be,

    edid_vendor[2] = (edid->mfg_id[1] & 0x1f) +  '@';

Since vendor ID has only two bytes only, I am somewhat surprised why gcc
doesn't complain this.
