| |
The CONFIG_PM doesn't actually enable any of the PM callbacks, it only allows to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. This means if CONFIG_PM is used to protect system sleep callbacks then it may end up unreferenced if only runtime PM is enabled. Hence protecting sleep callbacks with CONFIG_PM_SLEEP.
Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> --- This patch will remove the compilation warning if CONFIG_PM_SLEEP is not enabled.
Change from V1 ->V2: provide more details in description as per Mark's response.
