X-Git-Tag: next-20130326~77^2^2~52
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4a2cea4f2fd9c935f30666e4acdb1065ff60544;p=karo-tx-linux.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.
