From 0808da36b982442afc4a34555e492a16f2e5973e Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Fri, 1 Aug 2025 11:47:10 -0400 Subject: [PATCH] ALSA: usb-audio: Don't use printk_ratelimit for debug prints printk_ratelimit is deprecated, since it shares state with all other printk sites. Additionally, the suppression message is printed at warning level even though the actual messages are printed at debug and are (usually) invisible! This can result in thousands of messages like retire_capture_urb: 4992 callbacks suppressed in the console, and can inhibit debugging since it is unclear what the source of the suppressed callbacks is. Switch to dev_dbg_ratelimited which doesn't print anything unless debug is enabled.
