5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ghanshyam Agrawal <ghanshyam1898@xxxxxxxxx>
[ Upstream commit b3695e86d25aafbe175dd51f6aaf6f68d341d590 ]
The function stk1160_dbg gets called too many times, which causes
the output to get flooded with messages. Since stk1160_dbg uses
printk, it is now replaced with printk_ratelimited.
