From 03df65a0bc5e15e7c4cc7463cccfd86bc3c01a66 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 16 May 2018 20:07:18 +0200 Subject: ALSA: usb-audio: Apply rate limit to warning messages in URB complete callback [ Upstream commit 377a879d9832f4ba69bd6a1fc996bb4181b1e504 ] retire_capture_urb() may print warning messages when the given URB doesn't align, and this may flood the system log easily. Put the rate limit to the message for avoiding it.
