[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> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
