[PATCH v2] ASoC: xtensa: Use dev_err_probe() and drop redundant error handling

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

Convert error paths with messages to dev_err_probe(), which combines
dev_err() and the return statement while also handling -EPROBE_DEFER
for the clock path.
Remove the redundant "err:" label and return errors directly. Paths such
as platform_get_irq() already log failures in the callee, so they simply
return the error code without printing an additional message. Inline the
pm_runtime_disable() cleanup at its only call site.

No functional change.
