Subject: [media] tw9603/6.c: use two separate const tables for the 50/60hz setup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d4a2cea4f2fd9c935f30666e4acdb1065ff60544;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[media] tw9603/6.c: use two separate const tables for the 50/60hz setup

Using two separate tables to setup the registers for 50 or 60 hz is
better than the non-const table that is filled in at runtime.
