Subject: media: cec-funcs.h: cec_ops_report_features: set *dev_features to NULL
X-Git-Tag: v4.14-rc1~113^2~402

media: cec-funcs.h: cec_ops_report_features: set *dev_features to NULL

gcc can get confused by this code and it thinks dev_features can be
returned uninitialized. So initialize to NULL at the beginning to shut up
the warning.
