From: Ulf Hansson Date: Thu, 24 Sep 2020 11:04:47 +0000 (+0200) Subject: PM: domains: Rename power state enums for genpd X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=49f618e1b669ef0e26a8d8d7f8fafc7b8fd31531;p=linux.git PM: domains: Rename power state enums for genpd To clarify the code a bit, let's rename GPD_STATE_ACTIVE into GENPD_STATE_ON and GPD_STATE_POWER_OFF to GENPD_STATE_OFF.
