Subject: [PATCH] watchdog: core: Fix devres_alloc() allocation size
Date: Tue, 9 Aug 2016 22:34:31 -0700 [thread overview]
Message-ID: <1470807271-8723-1-git-send-email-linux@roeck-us.net> (raw)
Coverity reports:
Passing argument 152UL /* sizeof (*wdd) */ to function __devres_alloc_node
and then casting the return value to struct watchdog_device ** is
suspicious.
Allocation size needs to be sizeof(*rcwdd), not sizeof(*wdd).
Fixes: 83fbae5a148c ("watchdog: Add a device managed API for ...")
