[PATCH 13/44] tty: 8250/serial_cs, propagate errors in simple_config

From: Jiri Slaby
Date: Tue Mar 02 2021 - 03:23:00 EST


The caller expects from the others (pfc_config and multi_config) to
return standard error values. So do the same for simple_config too.

We invert the if condition to handle the error case.
