The #ifdef checks are hard to get right, in this case some functions
should have been left inside a CONFIG_PM_SLEEP check as seen by this
message:
drivers/net/wireless/ath/wil6210/pcie_bus.c:489:12: error: 'wil6210_pm_resume'
defined but not used [-Werror=unused-function]
drivers/net/wireless/ath/wil6210/pcie_bus.c:484:12: error: 'wil6210_pm_suspend'
defined but not used [-Werror=unused-function]
Using an __maybe_unused is easier here, so I'm replacing all the
other #ifdef in this file as well for consistency.
