Pull sound updates from Takashi Iwai:
 "No surprises in this development cycle, and most of work is about the
  fixes and the improvements of the existing code, while a new LED
  control layer and a few new drivers have been introduced.

  Here are some highlights:

  Core:
   - A common mute-LED framework was introduced. It is used by HD-audio
     for now, more adaption will follow later. The former "Mic Mute-LED
     Mode" mixer control has been replaced with the corresponding sysfs
     now.
   - User-control management was changed to count consumed bytes instead
     of capping by number of elements; this will allow more controls in
     the normal usage pattern while avoiding the possible memory
     exhaustion DoS

  ASoC:
   - Continued refactoring and cleanups in ASoC core and generic card
     drivers
   - Wide range of small cppcheck and warning fixes
   - New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
     accessory detection, and Realtek RT1019, RT1316, RT711 and RT715

  USB-audio:
   - Continued improvements and fixes of the implicit feedback mode,
     including better support for Pioneer and Roland/BOSS devices

  HD-audio:
   - Default back to non-buffer preallocation on x86
   - Cirrus codec improvements, more quirks for Realtek codecs

  Others:
   - New virtio sound driver
   - FireWire Bebob updates"

2021-04-27T17:16:46+00:00

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

  Summary:

   - Clean up list_sort prototypes (Sami Tolvanen)

   - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"

2021-04-26T23:32:11+00:00

Pull spi updates from Mark Brown:
 "The only core work for SPI this time around is the completion of the
  conversion to the new style method for specifying transfer delays,
  meaning we can cope with what most controllers support more directly
  using conversions in the core rather than open coding in drivers.

  Otherwise it's a good stack of cleanups and fixes plus a few new
  drivers.

  Summary:

   - Completion of the conversion to new style transfer delay
     configuration

   - Introduction and use of module_parport_driver() helper, merged here
     as there's no parport tree

   - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon
     Kunpeng, MediaTek MT8195"

The enable1 is confusing name. Change it to clearly show what is
the intention behind it. No functional changes.

spi: stm32-qspi: fix debug format string

2021-04-22T15:30:40+00:00

Printing size_t needs a special %zx format modifier to avoid a
warning like:

drivers/spi/spi-stm32-qspi.c:481:41: note: format string is defined here
  481 |         dev_dbg(qspi->dev, "%s len = 0x%x offs = 0x%llx buf = 0x%p\n", __func__, len, offs, buf);

Patrice already tried to fix this, but picked %lx instead of %zx,
which fixed some architectures but broke others in the same way.
Using %zx works everywhere.

spi: fsi: add a missing of_node_put

2021-04-21T15:07:04+00:00

'for_each_available_child_of_node' performs an of_node_get on each
iteration, so a return from the middle of the loop requires an of_node_put.

spi: Make error handling of gpiod_count() call cleaner

2021-04-21T15:07:04+00:00

Each time we call spi_get_gpio_descs() the num_chipselect is overwritten
either by new value or by the old one. This is an extra operation in case
gpiod_count() returns an error. Besides that it slashes the error handling
of gpiod_count().

Refactor the code to make error handling of gpiod_count() call cleaner.

Note, that gpiod_count() never returns 0, take this into account as well.
