[PATCH v2 0/5] spi: lock context annotations

[Joseph CT Chan <jctchan@gmail.com>]

From: Joseph CT Chan <josephctchan@google.com>

Hi Mark,

These are Bart Van Assche's patches, which I am carrying for him. They
add Clang lock context annotations for the SPI bus_lock_mutex, spi-mem
and microchip-core-qspi, split spi_write_then_read() so its buffer lock
can be checked, and turn on context analysis for drivers/spi and its
KUnit tests.

Tested by building with Clang 23.1.4 (kernel.org prebuilt toolchain)
and CONFIG_WARN_CONTEXT_ANALYSIS=y, with and without the other three
series applied, and running the SPI KUnit tests on ARCH=um. Not tested
on hardware.

Changes in v2:
- Split out of the v1 14-patch series, as David suggested. No code
  changes.

v1: https://lore.kernel.org/all/20261102163023.2574632-1-jctchan@gmail.com/

This series depends on the SPI core series ("spi: unoptimize message
when queuing it fails" v2), because patch 5 touches the KUnit Makefile
that series adds to. It applies before or after the spi-mux and
spi-ti-qspi series.

SPI core series v2: https://lore.kernel.org/linux-spi/20261103224753.3610049-1-jctchan@gmail.com/

Please consider this patch series for the next merge window.

Thanks,
Joseph
