[PATCH 6.12 696/826] spi: Fix acpi deferred irq probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stanislaw Gruszka <stanislaw.gruszka@xxxxxxxxxxxxxxx>

commit d24cfee7f63d6b44d45a67c5662bd1cc48e8b3ca upstream.

When probing spi device take care of deferred probe of ACPI irq gpio
similar like for OF/DT case.

>From practical standpoint this fixes issue with vsc-tp driver on
Dell XP 9340 laptop, which try to request interrupt with spi->irq
equal to -EPROBE_DEFER and fail to probe with the following error:

vsc-tp spi-INTC10D0:00: probe with driver vsc-tp failed with error -22
