Subject: [PATCH 2/2] selftests/user_events: Add non-spacing separator check
Date: Tue, 16 Apr 2024 22:41:02 +0000 [thread overview]
Message-ID: <20240416224102.734-3-beaub@linux.microsoft.com> (raw)
In-Reply-To: <20240416224102.734-1-beaub@linux.microsoft.com>
The ABI documentation indicates that field separators do not need a
space between them, only a ';'. When no spacing is used, the register
must work. Any subsequent register, with or without spaces, must match
and not return -EADDRINUSE.
Add a non-spacing separator case to our self-test register case to ensure
it works going forward.
