From 2e91838bf7ffdedabdb29e091207d6531d04ef4f Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Tue, 9 Aug 2016 22:34:31 -0700 Subject: [PATCH] watchdog: core: Fix devres_alloc() allocation size 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 ...")
