Merge tag 'spi-fix-v6.13-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown:
"A few fairly minor driver specific fixes, plus one core fix for the
handling of deferred probe on ACPI systems - ignoring probe deferral
and incorrectly treating it like a fatal error while parsing the
generic ACPI bindings for SPI devices"
* tag 'spi-fix-v6.13-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
spi: Fix acpi deferred irq probe
spi: atmel-quadspi: Fix register name in verbose logging function
spi-imx: prevent overflow when estimating transfer time
spi: rockchip-sfc: Embedded DMA only support 4B aligned address
