A DVB demultiplexer device can be used to set up either a PES filter or
a section filter. In the former case, the ts field of the feed union of
struct dmxdev_filter is used, in the latter case the sec field of the
same union is used.
The ts field is a struct list_head, and is currently initialized in the
open() method of the demux device. When for a given demuxer a section
filter is set up, the sec field is played with, thus if a PES filter
needs to be set up after that the ts field will be corrupted, causing a
kernel oops.
This fix moves the list head initialization to
dvb_dmxdev_pes_filter_set(), so that the ts field is properly
initialized every time a PES filter is set up.

As dvb_dmx_swfilter_packet() is protected by a spinlock, it shouldn't sleep.
However, vmalloc() may call sleep. So, move the initialization of
dvb_demux::cnt_storage field to a better place.

dvb_dmx_init tries to allocate virtual memory for 2 pointers: filter and feed.
If the second vmalloc fails, filter is freed, but the pointer keeps pointing
to the old place. Later, when dvb_dmx_release() is called, it will try to
free an already freed memory, causing an OOPS.

Different motherboards have different PNP declarations for
W83781D/W83782D chips. Some declare the whole range of I/O ports (8
ports), some declare only the useful ports (2 ports at offset 5) and
some declare fancy ranges, for example 4 ports at offset 4. To
properly handle all cases, request all ports individually for probing.
After we have determined that we really have a W83781D or W83782D
chip, the useful port range will be requested again, as a single
block.
I did not see a board which needs this yet, but I know of one for lm78
driver and I'd like to keep the logic of these two drivers in sync.

The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the
for loops that use this as a limit count are of the typical form, "for
(n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages
w/o missing the last one it is necessary for the count to be one greater
than it is. (Specifically, you will miss the +1.5V 3GPIO input with count
= 12 vs. 13.)

The new cs5535-* drivers use PCI header config info rather than MSRs to
determine the memory region to use for things like GPIOs and MFGPTs. As
anticipated, we've run into a buggy BIOS:
[ 0.081818] pci 0000:00:14.0: reg 10: [io 0x6000-0x7fff]
[ 0.081906] pci 0000:00:14.0: reg 14: [io 0x6100-0x61ff]

[ 0.084436] pci 0000:00:15.1: reg 10: [mem 0xa0011000-0xa0011fff]
[ 0.088816] PCI: pci_cache_line_size set to 32 bytes

[ 0.089052] pci 0000:00:14.0: can't reserve [io 0x6100-0x61ff]
This is a Soekris board, and its BIOS sets the size of the PCI ISA bridge
device's BAR0 to 8k. In reality, it should be 8 bytes (BAR0 is used for
SMBus stuff). This quirk checks for an incorrect size, and resets it
accordingly.

In suspend path we unmap the GART table while in cleaning up
path we will unbind buffer and thus try to write to unmapped
GART leading to oops. In order to avoid this we don't call the
suspend path in cleanup path. Cleanup path is clever enough
to desactive GPU like the suspend path is doing, thus this was
redondant.
