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. [akpm@linux-foundation.org: fix warning] Signed-off-by: Bjorn Helgaas Cc: Adam Belay Cc: Len Brown Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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. Signed-off-by: Bjorn Helgaas Acked-by: Adam Belay Signed-off-by: Len Brown

[PATCH] pnp: PNP: adjust pnp_register_driver signature

2006-03-27T16:44:53+00:00

Remove the assumption that pnp_register_driver() returns the number of devices claimed. Returning the count is unreliable because devices may be hot-plugged in the future. This changes the convention to "zero for success, or a negative error value," which matches pci_register_driver(), acpi_bus_register_driver(), and platform_driver_register().
