spi: spidev: Remove redundant initialization of variable status

In spidev_read() and spidev_write(), the variable status is being
initialized with a value that is never read and it is being updated
later with a new value. The initialization is redundant and can be
removed.

Merge tag 'spi-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
"A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity.

This includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the
memory subsystem doesn't seem to have a fixed maintainer at the minute
and this seemed like the most sensible way to get that hardware
supported.

- Quite a few cleanups and optimizations for the Altera, Qualcomm
GENI, sun6i and lantiq drivers.

- Several more GPIO descriptor conversions.

- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.

- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1"

ASoC: Updates for v5.9

The biggest changes here one again come from Mormioto-san who has
continued his dilligent work cleaning up long standing issues in the
APIs, it's particularly nice to see the transition from digital_mute()
to mute_stream() finally completed. There's also been a lot of work on
the x86 code again, this time a big focus has been on cleaning up some
issues identified by various static tests, and on the Freescale systems.
Otherwise the biggest thing has been a lot of driver additions:

- Convert users of digital_mute() to mute_stream().
- Simplify I/O helper functions.
- Add a helper for getting the RTD from a substream.
- Many, many fixes and cleanups to the x86 code.
- New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim
MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia
Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some
of the first phones I worked on!) and TI J721e EVM.

spi: spidev: Align buffers for DMA

Simply copying all xfers from userspace into one bounce buffer causes
alignment problems if the SPI controller uses DMA.

Ensure that all transfer data blocks within the rx and tx bounce buffers
are aligned for DMA (according to ARCH_KMALLOC_MINALIGN).

Alignment may increase the usage of the bounce buffers. In some cases,
the buffers may need to be increased using the "bufsiz" module
parameter.
