Subject: Staging: panel: Reduce value range for *name
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=52ebf93f367f3b749a696dc77ac2e42c186eb924;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Staging: panel: Reduce value range for *name

out is 0-9 so it's too much for om, therefore reduce value range for
*name from '0'-'9' to '0'-'7'.
