The current shift of st->rx[2] left shifts a u8 24 bits left,
promotes the integer to a an int and then to a unsigned u64. If
the top bit of st->rx[2] is set then we end up with all the upper
bits being set to 1. Fix this by casting st->rx[2] to a u64 before
the 24 bit left shift.

    drivers/iio/pressure/zpa2326.c:868: warning: ‘ret’ may be used uninitialized in this function

When testing for "timeout < 0", timeout is already guaranteed to be
strict negative, so the branch is always taken, and ret is thus always
initialized.  But (some version of) gcc is not smart enough to notice.

Remove the check to fix this.
As there is no other code in between assigning the error codes and
returning them, the error codes can be returned immediately, and the
intermediate variable can be dropped.

Jonathan writes:

First round of IIO fixes for the 4.14 cycle

Note this includes fixes from recent merge window.  As such the tree
is based on top of a prior staging/staging-next tree.

* iio core
  - return and error for a failed read_reg debugfs call rather than
    eating the error.
* ad7192
  - Use the dedicated reset function in the ad_sigma_delta library
    instead of an spi transfer with the data on the stack which
    could cause problems with DMA.
* ad7793
  - Implement a dedicate reset function in the ad_sigma_delta library
    and use it to correctly reset this part.
* bme280
  - ctrl_reg write must occur after any register writes
  for updates to take effect.
* mcp320x
  - negative voltage readout was broken.
  - Fix an oops on module unload due to spi_set_drvdata not being called
    in probe.
* st_magn
  - Fix the data ready line configuration for the lis3mdl. It is not
    configurable so the st_magn core was assuming it didn't exist
    and so wasn't consuming interrupts resulting in an unhandled
    interrupt.
* stm32-adc
  - off by one error on max channels checking.
* stm32-timer
  - preset should not be buffered - reorganising register writes avoids
  this.
  - fix a corner case in which write preset goes wrong when a timer is
  used first as a trigger then as a counter with preset. Odd case but
  you never know.
* ti-ads1015
  - Fix setting of comparator polarity by fixing bitfield definition.
* twl4030
  - Error path handling fix to cleanup in event of regulator
    registration failure.
  - Disable the vusb3v1 regulator correctly in error handling
  - Don't paper over a regulator enable failure.

Depends on: 691c4b95d1 ("iio: ad_sigma_delta: Implement a dedicated reset function")

SPI host drivers can use DMA to transfer data, so the buffer should be properly allocated.
Keeping it on the stack could cause an undefined behavior.

The dedicated reset function solves this issue.

The ctrl_reg register needs to be written after any write to
the humidity registers. The value written to the ctrl_reg register
does not necessarily need to change, but a write operation must
occur.

The regmap_update_bits functions will not write to a register
if the register value matches the value to be written. This saves
unnecessary bus operations.  The change in this patch forces a bus
write during the chip_config operation by switching to
regmap_write_bits.

This will fix issues where the Humidity Sensor Oversampling bits
are not updated after initialization.

Commit f686a36b ("iio: adc: mcp320x: Add support for mcp3301")
returns a signed voltage from mcp320x_adc_conversion() but neglects that
the caller interprets a negative return value as failure.  Only mcp3301
(and the upcoming mcp3550/1/3) is affected as the other chips are
incapable of measuring negative voltages.

Fix and while at it, add mcp3301 to the list of supported chips at the

When cursor is at beginning of an empty or whitespace-only line and
speakup-r typed, kernel locks up. This happens because deadlock of in
input_event function over dev->event_lock, as demonstrated by lockdep
logs. The reason for that is speakup simulates a down arrow - because
cursor is at an empty line - while inside key press notifier handler
which is ultimately triggered from input_event function. The simulated
key press leads to input_event being called again, this time under its
own context. So the spinlock is dev->event_lock is acquired while still
being held.

This patch ensures that key press is not simulated from inside key press
notifier handler. Instead it delegates to cursor_timer. It starts the
timer and passes RA_DOWN_ARROW as argument. When timer handler runs and
sees RA_DOWN_ARROW, it will then call kbd_fakekey2(RA_DOWN_ARROW) which
will correctly simulate the keypress inside timer context.

When not inside key press notifier callback, the behaviour will remain
the same as before this patch.

The function init_unisys() references
the function __init visorutil_spar_detect().
This is often because init_unisys lacks a __init
annotation or the annotation of visorutil_spar_detect is wrong.

It appears that newer versions inline visorutil_spar_detect(),
end up with an empty __init section. This marks the module
entry points as __init and __exit respectively, which avoids
