simplify pnp_activate_dev() and pnp_disable_dev() return values

2008-02-06T18:41:19+00:00

Make pnp_activate_dev() and pnp_disable_dev() return only 0 (success) or a negative error value, as pci_enable_device() and pci_disable_device() do. Previously they returned: 0: device was already active (or disabled) 1: we just activated (or disabled) device <0: -EBUSY or error from pnp_start_dev() (or pnp_stop_dev()) Now we return only 0 (device is active or disabled) or <0 (error). All in-tree callers either ignore the return values or check only for errors (negative values). Signed-off-by: Bjorn Helgaas Cc: Adam Belay Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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: don't fail device init if no DMA channel available

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

Most drivers for devices supporting ISA DMA can operate without DMA as well (falling back zo PIO). Thus it seems inappropriate for PNP to fail device initialization in case none of the possible DMA channels are available. Instead, it should be left to the driver to decide what to do if request_dma() fails. The patch at once adjusts the code to account for the fact that pnp_assign_dma() now doesn't need to report failure anymore.

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] reduce pnp syslog spam

2007-03-17T02:25:02+00:00

Make some normal code paths in PNP stop issuing syslog spam. Since PNP issues calls regardless of device capablities, it's no surprise when some of those devices don't support those calls! Signed-off-by: David Brownell Cc: Adam Belay Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
