[PATCH] fix a pile of OMAP issues

[Russell King - ARM Linux <linux@arm.linux.org.uk>]

This patch fixes a number of sillies, from missing 'const' to using
'return' in void functions, to functions with no arguments not even
'void' and a cast which isn't required.

Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

I want to merge this for the next ARM kernel pull by Linus.  Please
ack the patch.
