Subject: input: Separate out keyboard repeat/delay from init
X-Git-Tag: v2013.01-rc1~245
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1b1d3e6461e9195f825d6d8aa6a2a0e1e3188f62;p=oweals%2Fu-boot.git

input: Separate out keyboard repeat/delay from init

It is inconvenient to have to specify the keyboard repeat and delay at
init time if it is not yet available, so move this into a separate
function.

Some drivers will want to do this when their keyboard init routine
is actually called.
