H A D | wm8350_wdt.c | cfca31ce Thu May 27 07:32:24 CDT 2010 Julia Lawall <julia@diku.dk> [PATCH 2/11] drivers/watchdog: Eliminate a NULL pointer dereference
At the point of the call to dev_err, wm8350 is NULL.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @r exists@ expression E,E1; identifier f; statement S1,S2,S3; @@
if ((E == NULL && ...) || ...) { ... when != if (...) S1 else S2 when != E = E1 * E->f ... when any return ...; } else S3 // </smpl>
