Yes, I did use tools/checkpach from u-boot-samsung to verify style errors
in these patches, I didn't get any. It shows 0 errors and 0 warnings for
all 4 patches. No wonder, there could be few things which checkpatch might
not have caught. Please let me know the errors, I'll rectify them.
And also, I am pushing one more revision for PMIC set-voltage patch
with function comment. Please review it.
