From 368fd81d2db26e3338c7f42778a695510aff31b3 Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Sun, 5 Apr 2009 06:39:33 +0000 Subject: bas_gigaset: use tasklet_hi_schedule for timing critical tasklets The tasklets for isochronous data transfer need to run within 8 msec to avoid over/underruns, so schedule them with high priority to fix reported issues with occasional over/underruns.
