Gustavo A. R. Silva b72d39b1da PM / devfreq: Fix potential NULL pointer dereference in governor_store ... [ Upstream commit 63f1e05f7f ] df->governor is being dereferenced before it is null checked, hence there is a potential null pointer dereference. Notice that df->governor is being null checked at line 1004: if (df->governor) {, which implies it might be null. Fix this by null checking df->governor before dereferencing it.
