Takashi Iwai 5adfd8c266 ALSA: trident: Allocate resources with device-managed APIs 
This patch converts the resource management in PCI trident driver with
devres as a clean up.  Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.

This should give no user-visible functional changes.

snd_trident_interrupt
Description: ISR for Trident 4DWave device
Parameters: trident - device specific private data for 4DWave card
Problems: It seems that Trident chips generates interrupts more than
one time in special cases. The spurious interrupts are
detected via sample timer (T4D_STIMER) and computing
corresponding delta value. The limits are detected with
the method try & fail so it is possible that it won't
work on all computers. [jaroslav]
Returns: None.
