PM / yenta: Split resume into early and late parts (rev. 4)

2009-11-03T09:54:58+00:00

Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c
(PM / yenta: Fix cardbus suspend/resume regression) caused resume to
fail on systems with two CardBus bridges.  While the exact nature
of the failure is not known at the moment, it can be worked around by
splitting the yenta resume into an early part, executed during the
early phase of resume, that will only resume the socket and power it
up if there was a card in it during suspend, and a late part,
executed during "regular" resume, that will carry out all of the
remaining yenta resume operations.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a
listed regression from 2.6.31.

PM / yenta: Fix cardbus suspend/resume regression

2009-09-28T22:11:03+00:00

Since 2.6.29 the PCI PM core have been restoring the standard
configuration registers of PCI devices in the early phase of
resume.  In particular, PCI devices without drivers have been handled
this way since commit 355a72d75b3b4f4877db4c9070c798238028ecb5
(PCI: Rework default handling of suspend and resume).  Unfortunately,
this leads to post-resume problems with CardBus devices which cannot
be accessed in the early phase of resume, because the sockets they
are on have not been woken up yet at that point.

To solve this problem, move the yenta socket resume to the early
phase of resume and, analogously, move the suspend of it to the late
phase of suspend.  Additionally, remove some unnecessary PCI code
from the yenta socket's resume routine.

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a
post-2.6.28 regression.

PM / PCMCIA: Drop second argument of pcmcia_socket_dev_suspend()

2009-09-28T22:10:41+00:00

pcmcia_socket_dev_suspend() doesn't use its second argument, so it
may be dropped safely.

This change is necessary for the subsequent yenta suspend/resume fix.

pcmcia: yenta: add missing __devexit marking

2009-09-22T14:17:42+00:00

The remove member of the pci_driver yenta_cardbus_driver uses
__devexit_p(), so the remove function itself should be marked with
__devexit.  Even more so considering the probe function is marked with
__devinit.

Fix kernel-doc comments in drivers/pcmcia/:

- ti113x.h does not contain kernel-doc, so don't use /** to begin a doc
  comment
- yenta_socket.c: remove /** on non-kernel-doc comments;
  escape the ':' in an "http:" comment so that it won't be treated as a
  section heading;
- cs.c: remove /** on non-kernel-doc comments & add function parameter info
- ds.c: fix function parameter info

[PATCH] remove many unneeded #includes of sched.h

2007-02-14T16:09:54+00:00

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Driver core: convert pcmcia code to use struct device

2007-02-07T18:37:11+00:00

Converts from using struct "class_device" to "struct device" making
everything show up properly in /sys/devices/ with symlinks from the
/sys/class directory.
