[PATCH 5.13 203/300] i2c: synquacer: fix deferred probing
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Subsystem:
i2c subsystem, i2c subsystem host drivers, socionext synquacer i2c driver, the rest · Maintainers:
Andi Shyti, Ard Biesheuvel, Linus Torvalds
From: Sergey Shtylyov <redacted>
[ Upstream commit 8d744da241b81f4211f4813b0d3c1981326fa9ca ]
The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.
Fixes: 0d676a6c4390 ("i2c: add support for Socionext SynQuacer I2C controller")
