staging: comedi: 8255_pci: initialize MITE data window

2014-04-22T23:49:20+00:00

commit 268d1e799663b795cba15c64f5d29407786a9dd4 upstream.

According to National Instruments' PCI-DIO-96/PXI-6508/PCI-6503 User
Manual, the physical address in PCI BAR1 needs to be OR'ed with 0x80 and
written to register offset 0xC0 in the "MITE" registers (BAR0).  Do so
during initialization of the National Instruments boards handled by the
"8255_pci" driver.  The boards were previously handled by the
"ni_pcidio" driver, where the initialization was done by `mite_setup()`
in the "mite" module.  The "mite" module comes with too much extra
baggage for the "8255_pci" driver to deal with so use a local, simpler
initialization function.

zram: avoid null access when fail to alloc meta

2014-03-24T04:43:58+00:00

commit db5d711e2db776f18219b033e5dc4fb7e4264dd7 upstream.

zram_meta_alloc could fail so caller should check it.  Otherwise, your
system will hang.

staging:iio:adc:MXS:LRADC: fix touchscreen statemachine

2014-03-07T06:06:26+00:00

commit 760dbe1dcb6d3dd3ead73dc69b23f206b52273bb upstream.

Releasing the touchscreen lets the internal statemachine left in a wrong state.
Due to this the release coordinate will be reported again by accident when the next
touchscreen event happens. This change sets up the correct state when waiting
for the next touchscreen event.

This has led to reported issues with calibrating the touchscreen.
Bug was introduced somewhere in the series that began with

Staging/iio/adc/touchscreen/MXS: add proper clock handling
in which the way this driver worked was substantially changed
to be interrupt driven rather than relying on a busy loop.
This was a regression in the 3.13 kernel.

staging: binder: Fix death notifications

2014-03-07T06:06:25+00:00

commit e194fd8a5d8e0a7eeed239a8534460724b62fe2d upstream.

The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the
node release code to a separate function broke death notifications in
some cases. When it encountered a reference without a death
notification request, it would skip looking at the remaining
references, and therefore fail to send death notifications for them.

iio_kfifo_allocate returns NULL in case of error.

staging: comedi: adv_pci1710: fix analog output readback value

2014-02-22T21:34:50+00:00

commit 1e85c1ea1ff2a60659e790ef8ec76c7339445841 upstream.

The last value written to a analog output channel is cached in the
private data of this driver for readback.

Currently, the wrong value is cached in the (*insn_write) functions.
The current code stores the data[n] value for readback afer the loop
has written all the values. At this time 'n' points past the end of
the data array.

Fix the functions by using a local variable to hold the data being
written to the analog output channel. This variable is then used
after the loop is complete to store the readback value. The current
value is retrieved before the loop in case no values are actually
written..

staging: r8188eu: Fix typo in USB_DEVICE list

commit 08951f10ae146d0c4114ac508310ad316b6f8798 upstream.

There is a typo in the device list that interchanges the vendor and
product codes for one of the entries. This exchange was determined
by noticing that the vendor code is 0x07b8 for Abocom at
http://www.linux-usb.org/usb.ids.
