staging: comedi: me_daq: remove broken workaround for PLX bug
The PLX PCI 9050 interface chip has a bug where its local configuration
registers accessible through PCI BAR 0 and/or PCI BAR 1 (depending on
settings loaded from a serial EEPROM or local bus processor) are
unreadable (always read 0 instead of the true register values) if the
base address starts on an odd multiple of 0x80 (i.e. has bit 7 set to
1).
The "me_daq" driver attempts to work around this by writing to the PCI
config space to swap the addresses assigned to PCI BAR 0 and PCI BAR 5
(which has been initially configured by serial EEPROM load as a spare
region of the same length as the PCI BAR 0 region). (If the PCI BAR 5
region is absent, it attempts to reduce the PCI BAR 0 address by 0x80,
which is likely to cause havoc for some other device, but that case
shouldn't be reachable in practice.)
The workaround in the driver is ineffective because it has already
ioremapped the memory from `pci_resource_start(pcidev, 0)` *before* it
does the workaround, so after swapping PCI BAR 0 and PCI BAR 5, this
memory will end up accessing whatever onboard registers PCI BAR 5 was
linked to instead of the local configuration registers. It also leaves
the addresses in the physical PCI BAR registers set differently to the
resource start addresses recorded in the `struct pci_dev`.
The workaround could be fixed by ioremapping `pci_resource_start(pcidev,
5)` if the PCI BAR addresses were physically swapped (and the fallback
workaround of subtracting 0x80 from the base address should really be
removed altogether). However, it's not really worth it. This sort of
thing should be worked around in "drivers/pci/quirks.c" by ensuring that
PCI BAR 0 and/or PCI BAR 1 do not end up on an odd multiple of 0x80
bytes.

From Jonathan:
"Fifth round of new IIO drivers, cleanups and fixes for the 3.8 cycle.
Here we have a number of minor fixes.
* a quirk for the hid sensor driver should be a boolean option.
* return an error for a failed memdup in the hid sensor driver.
* Fix a return value in adt7410.
* A double free in the IIO event infrastructure.
* Disabling interrupts in tsl2563 was wrong (never been correct!)
* Incorrect signature for the iio_buffer_register stub
* Incorrect return for isl29018 write_raw callback.
* A number of minor fixes as part of the various rework series.
New drivers and major rework.
* Introduce and use extensively an adis library for numerous spi
Analog Devices mems sensors. This then moves out of staging.
* Lots of new stuff then added to this library to support newer
sensors.
* New drivers for ADIS16136 and ADIS16480 and similar.
* Core support for barometric pressure sensors.
* ad7298 cleanup and move out of staging.
The bulk of this is from Lars-Peter Clausen. He's been rather
busy!"

Some of the newer generation devices from the ADIS16XXX series have more
registers than what can be supported with the current register addressing
scheme. These devices implement register paging to support a larger register
range. Each page is 128 registers large and the currently active page can be
selected via register 0x00 in each page. This patch implements transparent
paging inside the common adis library. The register read/write interface stays
the same and when a register is accessed the library automatically switches to
the correct page if it is not already selected. The page number is encoded in
the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

The recent cleanups have decimated the drivers code size by quite a bit. It is

include buffer support, instead of making it optional. This is more consistent
with what we do for other drivers.

For buffered mode we do not want to perform endianness conversion in the kernel,
but rather offload it to user space, since it is not always required to do a

post-processing has to be done and may allow future optimizations like streaming
data directly to a storage device or over the network via DMA.

Currently the driver reads out all sample registers of the device and throws
away those which it does not need. Furthermore the SPI message is constructed
each time the trigger handler is run, although it will be the same each time.
This patch preallocates and pre-constructs the SPI message in the
"update_scan_mode" callback. Only those register which are actually selected for
sampling are included in the message. The patch also gets rid of the conversion
of the sample data from big endian to the native endianness and instead marks
the channel as big endian in its scan type. This allows to directly push the
SPI transfer buffer to the IIO buffer without the need to post-process it.
