[PATCH 5.15 39/75] ASoC: tlv320adcx140: Propagate error codes during probe

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: Dimitrios Katsaros <patcherwork@gmail.com>

[ Upstream commit d89aad92cfd15edbd704746f44c98fe687f9366f ]

When scanning for the reset pin, we could get an -EPROBE_DEFER.
The driver would assume that no reset pin had been defined,
which would mean that the chip would never be powered.

Now we both respect any error we get from devm_gpiod_get_optional.
We also now properly report the missing GPIO definition when
'gpio_reset' is NULL.
