Subject: drm/imx: parallel-display: reduce scope of edid_len
X-Git-Tag: v5.10-rc3~23^2~3^2~1
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=acbb7f1436624819f728742f781c7d5f10ba267d;p=linux-block.git

drm/imx: parallel-display: reduce scope of edid_len

The edid_len variable is never used again. Use a local variable instead
of storing it in the device structure.
