snd_hwdep_new and snd_seq_device_new

snd_hwdep_new and snd_seq_device_new

[Raymond]

There are functions snd_hwdep_free() and snd_seq_device_free(), they are 
not export_symbol


EXPORT_SYMBOL(snd_hwdep_new) in hwdep.c
EXPORT_SYMBOL(snd_seq_device_new) in seq/seq_device.c


Do I need to free the (soundfont loading) hwdep device on the callback
".dev_free" of the sound card ?

Do it mean that I cannot use snd_device_new(card, SNDRV_DEV_SEQUENCER, 
wt, &ops)) to implement a customized version of snd_seq_device_free()
(put the synth code in the sound card driver) ?

Nope. You may set hwdep->private_free and/or seqdev->private_free callback 
to cleanup/free your allocated data. See snd_seq_device_free() and 
snd_hwdep_free() implementation.
