If anyone has any objections, please let me know. ------------------ From: Takashi Iwai [ 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.
