sys/dev/sound/pci atiixp.c
Log:
MFC (revision 1.6)
Misc. fixups:
- [1] Make the driver friendly towards kernel without PREEMPTION.
Use msleep(9) instead of simple unlock-check_variable-lock
mechanisme since the later not really effective in non-preemptible
kernel (especially during codec detection routine).
- Free most driver resources in a sane manner to avoid possible
double free and panics especially during device detach and codec
detection failure.
