[linux-pm] [PATCH 1/2] PM: Fix freezer compilation if PM_SLEEP is unset

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw at sisk.pl>

Freezer fails to compile if with the following configuration
settings:

CONFIG_CGROUPS=y
CONFIG_CGROUP_FREEZER=y
CONFIG_MODULES=y
CONFIG_FREEZER=y
CONFIG_PM=y
CONFIG_PM_SLEEP=n

Fix this by making process.o compilation depend on CONFIG_FREEZER.
