Subject: s390/time: Fix clk type in get_tod_clock
From: Nathan Chancellor <natechancellor@xxxxxxxxx>
commit 0f8a206df7c920150d2aa45574fba0ab7ff6be4f upstream.

../arch/s390/include/asm/timex.h:149:44: note: passing argument to
parameter 'clk' here

Change clk's type to just be char so that it matches what happens in
get_tod_clock_ext.
