This patch just do some clean up to replace printk with pr_*, and introduces pr_fmt() to remove all PREFIXs in this file, no functional change. Signed-off-by: Hanjun Guo <hanjun.guo@linaro.org> --- Hi Rafael, I introduced pr_fmt() as Sudeep suggested, and remove all PREFIXs in this file, hope this patch is ok to you.
