Subject: [ARM] 3926/1: make timer led handle HZ != 100
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6d15cb42fe4f8c07c80c9d49db721fcfe2da0e90;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[ARM] 3926/1: make timer led handle HZ != 100

The timer LED is unusable at HZ=large, since it's got
a hard-wired value of 100 ticks per cycle; when HZ=1024
(for example) it's essentially always-on.  This patch
just makes that be HZ ticks per cycle.
