Merge tag 'spi-fix-v6.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi fixes from Mark Brown:
 "A few more device specific fixes plus one trivial quirk.

  There's a couple of patches for Tegra which avoid some fairly
  spectacular log spam if the hardware breaks in ways which were
  actually seen in production, plus a fix for the i.MX driver to
  propagate errors properly when setting up the hardware.

  We also have a trivial patch marking the sun4i driver as being
  compatible with GPIO chip selects"

* tag 'spi-fix-v6.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
  spi: spi-imx: Add check for spi_imx_setupxfer()
  spi: tegra210-quad: add rate limiting and simplify timeout error message
  spi: tegra210-quad: use WARN_ON_ONCE instead of WARN_ON for timeouts
  spi: sun4i: add support for GPIO chip select lines
