Subject: [PATCH v4 4/5] PCI/sysfs: Add missing trailing newline to devspec_show()
Date: Tue, 25 May 2021 12:24:00 +0000	[thread overview]
Message-ID: <20210525122401.206136-4-kw@linux.com> (raw)
In-Reply-To: <20210525122401.206136-1-kw@linux.com>

At the moment, when the value of the "devspec" sysfs object is read from
the user space there will be no newline present, and the utilities such
as the "cat" command won't display the result of the read correctly in
a shell, as the trailing newline is currently missing.

To fix this, append a newline character in the show() function.
