From: Carlos Eduardo Aguiar <carlos.aguiar@indt.org.br>
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.

From: Carlos Eduardo Aguiar <carlos.aguiar@indt.org.br>
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).
- Use if (ret) instead of if (ret != 0).
- Add an extra-line to separate labels.
