Dag-Erling Smørgrav 85cc3851ff Add some safeguards to AIOSFMT: ... - Return EINVAL if play_format or rec_format is set but the corresponding sample rate is 0. - Don't try to set the playback or recording format to 0. Previously, issuing an AIOSFMT ioctl with an all-zeroes snd_chan_param would trigger a KASSERT in chn_fmtchain(); I'm unsure about the effects on a kernel without INVARIANTS. After this commit, issuing AIOSFMT with an all-zeroes snd_chan_param is equivalent to issuing AIOGFMT. MFC after: 2 weeks		2005-10-30 10:03:11 +00:00
