In fact, the clk-mtk.h header is indeed not needed for reset.c and thus
it's safe and good change to remove it from the file.

drivers/clk/mediatek/reset.c:64:6: warning: symbol 'mtk_register_reset_controller' was not declared. Should it be static?

It cannot be static since the function would be referenced in other
files under the same folder
One point I felt confused which is I didn't see the warning complains
when I did these build test, even I also added -Werror and -Wall to
build all files under driver/clk/mediatek. My toolchain is based on gcc
version 5.2.0 (GCC).
If the warning still is, the include "clk-mtk.h" should be good to stay
there because the declaration it needs is in the clk-mtk.h

I tested and I get the warning here (gcc 4.8.5 on SUSE) but only after
setting CONFIG_RESET_CONTROLLER=y. Without it,
drivers/clk/mediatek/reset.o is never built, so no warning can be
generated.

Agreed.

The warning is from sparse. I built the file with C=2 on the
commandline.
