Subject: [PATCH] doc: mei: fix handling return value of mei_recv_msg
Date: Mon, 14 Dec 2015 11:05:59 +0100 [thread overview]
Message-ID: <1450087564-28441-2-git-send-email-a.hajda@samsung.com> (raw)
In-Reply-To: <1450087564-28441-1-git-send-email-a.hajda@samsung.com>
The function can return negative values, so its result should
be assigned to signed variable.
The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].
