[PATCH v12 1/4] serdev: Replace all instances of ENOTSUPP with EOPNOTSUPP

From: Neeraj Sanjay Kale
Date: Wed Mar 15 2023 - 08:04:30 EST


This replaces all instances of ENOTSUPP with EOPNOTSUPP since ENOTSUPP
is not a standard error code. This will help maintain consistency in
error codes when new serdev API's are added.
