[PATCH v1] thermal: brcmstb_thermal: Simplify with dev_err_probe()

From: Yan Zhen
Date: Fri Aug 30 2024 - 06:41:13 EST


dev_err_probe() is used to log an error message during the probe process
of a device.

It can simplify the error path and unify a message template.

Using this helper is totally fine even if err is known to never
be -EPROBE_DEFER.

The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.
