Subject: drm/imx: imx-ldb: reduce scope of edid_len
X-Git-Tag: v5.10-rc3~23^2~3^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=754e0b5803e4d915a6f6d8a4154491564c5ea17c;p=thirdparty%2Fkernel%2Flinux.git

drm/imx: imx-ldb: 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.
