a2bd5afd59 spi: lm70llp: add parenthesis for sizeof 
Fix missing parenthesis of sizeof reported by checkpatch.pl:
 WARNING: sizeof *pp should be sizeof(*pp).

The kernel coding style suggests thinking of sizeof as a function
and add parenthesis.

026a1dc1af spi: spi-topcliff-pch: Fix potential double free in pch_spi_process_messages() 
pch_spi_set_tx() frees data->pkt_tx_buff on failure of kzalloc() for
data->pkt_rx_buff, but its caller, pch_spi_process_messages(), will
free data->pkt_tx_buff again. Set data->pkt_tx_buff to NULL after
kfree() to avoid double free.

When the data structure is only referred by pointer, compiler may not need
to see the contents of the data type. Thus, we may replace header inclusions

b71428d7ab Merge tag 'sound-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound 
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"
