[PATCH] ALSA: snd-usb: fix next_packet_size calls for pause case

From: Daniel Mack
Date: Thu Sep 27 2012 - 04:26:20 EST


Also fix the calls to next_packet_size() for the pause case. This was
missed in 245baf983 ("ALSA: snd-usb: fix calls to next_packet_size").

Hi Linus,

Takashi is currently on vacation and asked me to contact you directly
for merging this patch for 3.6. FWIW, it's also available here:

Thanks,
Daniel
