leds: bugfixes for leds-gpio

Three bugfixes to the leds-gpio driver, plus minor whitespace tweaks:

 - Do the INIT_WORK() before registering each LED, so if its trigger
   becomes immediately active it can schedule work without oopsing..

 - Use normal registration, not platform_driver_probe(), so that
   devices appearing "late" (hotplug type) can still be bound.

 - Mark the driver remove code as "__devexit", preventing oopses
   when the underlying device is removed.

These issues came up when using this driver with some GPIO expanders
living on serial busses, which act unlike "normal" platform devices:
they can appear and vanish along with the serial bus driver.

12 years agoPCI: Remove 3 incorrect MSI quirks.
David Miller [Thu, 25 Oct 2007 08:17:16 +0000]
PCI: Remove 3 incorrect MSI quirks.

Now that we have dealt with the real issue, in that some ATI SATA and
USB controllers needed the INTX_DISABLE quirk, we can remove these AMD
chipset global MSI disabling quirks.

This reverts three changesets:

4be8f906435a6af241821ab5b94b2b12cb7d57d8 (PCI: disable MSI on RS690)
aea6a433f50cd89b9cbd10850fd0b32f961f9883 (PCI: disable MSI on RD580)
f122392f679ebed39db08074f935d770504623eb (PCI: disable MSI on RX790)

This is based upon testing and feedback from

12 years agoPCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.
David Miller [Thu, 25 Oct 2007 08:16:30 +0000]
PCI: Add quirk for devices which disable MSI when INTX_DISABLE is set.

A reasonably common problem with some devices is that they will
disable MSI generation when the INTX_DISABLE bit is set in the
PCI_COMMAND register.

Quirk this explicitly, guarding the pci_intx() calls in msi.c with
this quirk indication.

The first entries for this quirk are for 5714 and 5780 Tigon3 chips,
and thus we can remove the workaround code from the tg3.c driver.

12 years agoPCI: Add MSI quirk for ServerWorks HT1000 PCIX bridge.
David Miller [Thu, 25 Oct 2007 08:15:53 +0000]
PCI: Add MSI quirk for ServerWorks HT1000 PCIX bridge.

This is the fix for the following problem:

https://bugzilla.redhat.com/show_bug.cgi?id=227657

The bnx2 device 5706 complains about MSI not working behind a
ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem:

e3008dedff4bdc96a5f67224cd3d8d12237082a0:

"PCI: disable MSI by default on systems with Serverworks HT1000 chips"

was not entirely correct, and has been reverted.

MSI does not work on the PCIX bus because the BIOS did not set the
HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the
bridge.  We use the existing quirk_msi_ht_cap() to detect the problem
and disable MSI in all buses behind it.

SLUB: Fix memory leak by not reusing cpu_slab

Fix the memory leak that may occur when we attempt to reuse a cpu_slab
that was allocated while we reenabled interrupts in order to be able to
grow a slab cache.

The per cpu freelist may contain objects and in that situation we may
overwrite the per cpu freelist pointer loosing objects.  This only
occurs if we find that the concurrently allocated slab fits our
allocation needs.

If we simply always deactivate the slab then the freelist will be
properly reintegrated and the memory leak will go away.

V4L/DVB (6548): pvrusb2: Fix oops on module removal

The pvrusb2 driver is tearing down its sysfs related pieces in the
incorrect order.  This leaves dangling pointers which causes the
kernel device core to oops.  The problem has been present virtually
forever but became malignant with the changeover to the way of
handling /sys/class.  Fix is just to make sure we don't tear down the
class structure until AFTER the driver instances are deregistered.

It depends on some v4l headers included two levels down including poll.h,
which includes mm.h.

These v4l headers might change, so it's best to include the headers needed

You are right. The patch below (based on your cx88 patch, but I don't

V4L/DVB (6504): pvrusb2: Remove dead sysfs code

The pvrusb2 driver's sysfs implementation had long since implemented a
dummy hotplug function because at the time the kernel would oops
without at least the empty function being present.  Today - after
numerous class interface changes in the kernel - this pvrusb2 change
had been dutifully carried forward but an inspection of the kernel
sources shows that it is no longer needed.  So remove the dummy
function and its reference.  This also solves a recurring backwards
compatibility issue in the pvrusb2 driver as the class interface has
been getting thrashed in the kernel.

V4L/DVB (6392): bttv: Update initial image size when set via V4L1 VIDIOCMCAPTURE

The V4L1 spec says that the image size should be with with VIDIOCSWIN before
requesting buffers with VIDIOCGMBUF and capturing into them with
VIDIOCMCAPTURE.

But it seems that many apps don't do this.  They set the size using the fields
in the VIDIOCMCAPTURE ioctl.  The driver doesn't know what size to capture
until it actually starts to capture.  In particular, it doesn't know what size
to capture until it has already mmap the captured buffers.  Which is quite
stupid.  Why V4L1 has size and format fields for VIDIOCMCAPTURE I have no idea.

Many drivers don't support this, including those using v4l1-compat.

The bttv does, which is probably the only reason such broken software is so
prevalent.

But, the driver doesn't adjust its idea of what size is being captured when it
is set this way.  If you try to query the driver's current setting with
v4l2-ctl, it won't be correct.

12 years agoV4L/DVB (6391): bttv: SPICT ioctl doesn't work with vlc
Trent Piepho [Mon, 22 Oct 2007 20:44:54 +0000]
V4L/DVB (6391): bttv: SPICT ioctl doesn't work with vlc

The bttv driver instists that the depth specified in the call to VIDIOCSPICT
match the pixel format specified in the same call.

vlc doesn't set the depth field, which makes the SPICT ioctl always fail.

The V4L1 standard is not clear on how most operation are supposed to work, and
this is no exception.  The depth field would appear to be entirely redundant,
as the pixel format specifies a specific depth.  It could be that this field
was only meant for output from the *G*PICT ioctl and should be ignored in
*S*PICT.  This is in fact what the v4l1-compat wrapper does.
