Subject: [PATCH] wlcore: fix error handling in wlcore_event_fw_logger
Date: Thu, 07 Jan 2016 14:28:50 +0100 [thread overview]
Message-ID: <1452173330-19963-1-git-send-email-a.hajda@samsung.com> (raw)
wlcore_read/wlcore_write can return negative values so it should
be assigned to signed variable.
The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1].
