Subject: [PATCH] media: stk1160: Fixed high volume of stk1160_dbg messages
Date: Sun, 29 Oct 2023 20:06:04 +0530 [thread overview]
Message-ID: <20231029143604.120329-1-ghanshyam1898@gmail.com> (raw)
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 directly.
