Subject: [PATCH] PM: Add pm_ops_ptr() macro
Date: Sat, 27 Apr 2013 11:54:50 +0900 [thread overview]
Message-ID: <000001ce42f2$96128cc0$c237a640$@samsung.com> (raw)
Add pm_ops_ptr() macro that allows the .pm entry in the driver structures
to be assigned without having an #define xxx NULL for the case that PM is
not enabled.
