[PATCH 0/4] ALSA: ymfpci: PM related cleanups and fixes
Hi,
This series started while attempting to fix the OPL not being detected after restoring from S4 on a YMF744. While attempting to debug the issue, it was found that SIMPLE_DEV_PM_OPS was deprecated, and thus replaced, and a few cleanups were made along the way.
Tasos Sahanidis (4): ALSA: ymfpci: Switch to DEFINE_SIMPLE_DEV_PM_OPS() ALSA: ymfpci: Move allocation of saved registers to struct snd_ymfpci ALSA: ymfpci: Store saved legacy registers in an array ALSA: ymfpci: Store additional legacy registers on suspend

Since commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones") SIMPLE_DEV_PM_OPS has been marked deprecated.
The intent is to remove CONFIG_PM_SLEEP guards for PM callbacks. As such the ifdefs are now removed.

The registers were previously allocated when CONFIG_PM_SLEEP was set, however this only saved an insignificant amount of memory otherwise.

In preparation for storing more than two legacy PCI registers, the existing ones are moved into a new array.

YMF744 and newer store the base IO ports in separate PCI config registers.
Since these registers were not restored, when set to a non-default value, features that rely on them (FM, MPU401, gameport) were not functional after restore, as their respective IO ports were reset to their defaults.
