Subject: [PATCH v2 1/3] PM: introduce pm_ptr() macro
Date: Mon, 13 Apr 2020 14:32:05 +0200 [thread overview]
Message-ID: <20200413123207.74552-1-paul@crapouillou.net> (raw)
This macro is analogous to the infamous of_match_ptr(). If CONFIG_PM
is enabled, this macro will resolve to its argument, otherwise to NULL.
Signed-off-by: Paul Cercueil <paul@crapouillou.net>

v2: Remove pm_sleep_ptr() macro
