[ARM] 3246/1: S3C24XX - retab clock list in arch/arm/mach-s3c2410/clock.c
Patch from Ben Dooks Properly tabulate the clock table in arch/arm/mach-s3c2410/clock.c and put the requisite commas on the end of the structs. Fix the comment about clock enable and disable in the setup code Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
