PNP: change pnp_add_id() to allocate its own pnp_id structures

2008-04-29T07:22:16+00:00

This moves some of the pnp_id knowledge out of the backends and into
the PNP core.

PNP: skip dev->protocol NULL checks

2008-04-28T15:58:42+00:00

Every PNP device should have a valid protocol pointer.  If it doesn't,
something's wrong and we should oops so we can find and fix the problem.

PNP: do not test PNP_DRIVER_RES_DO_NOT_CHANGE on suspend/resume

2008-02-06T18:41:20+00:00

The PNP_DRIVER_RES_DO_NOT_CHANGE flag is meant to signify that the PNP core
should not change resources for the device -- not that it shouldn't
disable/enable the device on suspend/resume.

ALSA ISAPnP drivers set PNP_DRIVER_RES_DO_NOT_CHANAGE (0x0001) through
setting PNP_DRIVER_RES_DISABLE (0x0003).  The latter including the former
may in itself be considered rather unexpected but doesn't change that
suspend/resume wouldn't seem to have any business testing the flag.

As reported by Ondrej Zary for snd-cs4236, ALSA driven ISAPnP cards don't
survive swsusp hibernation with the resume skipping setting the resources
due to testing the flag -- the same test in the suspend path isn't enough
to keep hibernation from disabling the card it seems.

These tests were added (in 2005) by Piere Ossman in commit
68094e3251a664ee1389fcf179497237cbf78331, "alsa: Improved PnP suspend
support" who doesn't remember why.  This deletes them.

PNP: use dev_info(), dev_err(), etc in core

2007-10-17T15:43:04+00:00

If we have the struct pnp_dev available, we can use dev_info(), dev_err(),
etc., to give a little more information and consistency.

PNP: remove null pointer checks

2007-08-24T05:27:24+00:00

Remove some null pointer checks.  Null pointers in these areas indicate
programming errors, and I think it's better to oops immediately rather
than return an error that is easily ignored.
