PM / devfreq: Check governor before using governor->name

Browse source

[ Upstream commit bab7834c03 ]

Commit 96ffcdf239 ("PM / devfreq: Remove redundant governor_name from
struct devfreq") removes governor_name and uses governor->name to replace
it. But devfreq->governor may be NULL and directly using
devfreq->governor->name may cause null pointer exception. Move the check of
governor to before using governor->name.
