net: ethernet: oa_tc6: return ERR_PTR from oa_tc6_init()

Browse source

oa_tc6_init() returns NULL on failure, so the reason for the failure is
lost and both callers turn it into a plain -ENODEV. In preparation for
acquiring an optional reset GPIO, which can return -EPROBE_DEFER when the
GPIO provider is not available yet, the error code has to reach the driver
core, otherwise the SPI device would never be probed again.

Convert oa_tc6_init() to return an ERR_PTR on failure instead of NULL,
and update the lan865x and adin1140 callers to check with IS_ERR() and
propagate the error with PTR_ERR().
