4 Subject: [PATCH 5/5] PM / devfreq: passive: Return non-error when
5 not-supported event is required
6
7 Each devfreq governor specifies the supported governor event
8 such as GOV_START and GOV_STOP. When not-supported event is required,
9 just return non-error. But, commit ce9a0d88d97a ("PM / devfreq: Add
10 cpu based scaling support to passive governor") returned the error
11 value. So that return non-error value when not-supported event is required.
