[PATCH v2] drivers: char: hw_random: printk replacement

[Sudip Mukherjee]

as pr_* macros are more preffered over printk, so printk replaced with corresponding pr_* macros

Signed-off-by: Sudip Mukherjee <sudip@xxxxxxxxxxxxxxx>

The replacement was done by a bash script to avoid copy paste error. The script is as follows :

OLD="printk(KERN_ERR \?"
OLD1="printk(KERN_NOTICE \?"
OLD2="printk(KERN_WARNING \?"
OLD3="printk(KERN_INFO \?"
NEW="pr_err("
NEW1="pr_notice("
NEW2="pr_warn("
NEW3="pr_info("
TFILE="/tmp/out.tmp.$$"
for f in *.c
do
sed -e "s/$OLD/$NEW/g" -e "s/$OLD1/$NEW1/g" -e "s/$OLD2/$NEW2/g" -e "s/$OLD3/$NEW3/g" "$f" > $TFILE && mv $TFILE "$f"
done

exception is intel-rng.c . 
in v1 the build failed due to intel-rng.c . 
it has been corrected and has been carefully build tested.
