Subject: [PATCH v12 1/4] serdev: Replace all instances of ENOTSUPP with EOPNOTSUPP
Date: Wed, 15 Mar 2023 17:33:23 +0530	[thread overview]
Message-ID: <20230315120327.958413-2-neeraj.sanjaykale@nxp.com> (raw)
In-Reply-To: <20230315120327.958413-1-neeraj.sanjaykale@nxp.com>

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.
