Subject: [PATCH AUTOSEL 5.10 13/28] media: stk1160: Fixed high volume of stk1160_dbg messages
From: Ghanshyam Agrawal <ghanshyam1898@...il.com>
[ 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.
