Subject: serial: 8250_aspeed_vuart: Use dev_err_probe() instead of dev_err()
X-Git-Tag: v6.7-rc1~75^2~188
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e8bbaeac25503aaaf215e9cc4b278890e043410b;p=thirdparty%2Fkernel%2Fstable.git

serial: 8250_aspeed_vuart: Use dev_err_probe() instead of dev_err()

The probe process may generate EPROBE_DEFER. In this case
dev_err_probe() can still record err information. Otherwise
it may pollute logs on that occasion.

This also helps simplifing code and standardizing the error output.
