pluto2_driver: Workaround for pluto2 card reporting wrong number of
received packets and flooding system with interrupts.
This patch constitutes a workaround for a hardware/firmware problem of the
pluto2-based card (e.g., Satelco EasyWatch).
It can happen in rare cases that the card gets into a mode where it
always reports back a number of received packets (nbpackets) which is
larger than the maximum permissible number of packets (TS_DMA_PACKETS).
The workaround that is already in the driver in function pluto_dma_end
reports back zero received packets. In spite of the (in reality) zero
received packets the card continues to generate interrupts at a very
high rate, which can effectively stall the system.
The patch resets the TS logic, which puts the card back into normal
operations.

This causes the cx25840 module to treat V4L2_STD_PAL_60 similar to
other 60Hz timings, and it fixes a wrongly-named variable (timings are

Anyone using multiple PVR USB2 devices really only want one of them
acting as the actual IR receiver.
Implemented here is a new per-instance module option (ir_mode) which is
a flag to enable the IR receiver. The default is enabled.
IR reception is disabled by blocking access to the IR receiver chip in
the device.

This patch originated with Servaas Vandenberghe <vdb128@picaros.org>
and has been further developed a bit (to preserve saa7115 behavior).
These changes allow for correct operation of PAL-60 video (Servaas
tested this against a PAL-B/G tuner with the video standard overridden
as a module option).

sysfs is now completely out of driver/module lifetime game.
After deletion, a sysfs node doesn't access anything outside sysfs
proper, so there's no reason to hold onto the attribute owners.
Note that often the wrong modules were accounted for as owners leading
to accessing removed modules.
This patch kills now unnecessary attribute->owner.
Note that with this change, userland holding a sysfs node does not
prevent the backing module from being unloaded.

I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:

This shrinks the size of "struct i2c_client" by 40 bytes:
- Substantially shrinks the string used to identify the chip type
- The "flags" don't need to be so big
- Removes some internal padding
It also adds kerneldoc for that struct, explaining how "name" is really a
chip type identifier; it's otherwise potentially confusing.
Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name
and for i2c_adapter.name, this needed to affect i2c_adapter too. The
adapters which used that symbol now use the more-obviously-correct
idiom of taking the size of that field.
JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to
avoid wasting space in padding.
