Hi,
somehow this did not apply against linux-next for me:
error: patch failed: arch/arm/mach-exynos4/clock.c:1250

this would lead to the hsmmc1 hclk being registered twice, as it is already
registered in plat-s3c24xx/clock-2443.c .
How about the following, which also adds the lookup for the s3c2443-specific
hsmmc-sclk.
