> This patch makes the following general code cleanup and cosmetic fixes:
>
> - Use #include <linux/io.h> instead of <asm/io.h>, according to warning
> reported by scripts/checkpatch.pl on arch/arm/mach-omap2/board-sdp-hsmmc.c
>
> - Use if (power_on) instead of if (power_on == 1) and if (!power_on) instead
> of if (power_on == 0).
>
> - Use if (ret) instead of if (ret != 0).
>
> - Add an extra-line to separate labels.

I guess the above else if be just else with this patch?
