- * fw_pm_notify - notifier for suspend/resume
- * @notify_block: unused
- * @mode: mode we are switching to
- * @unused: unused
- *
- * Used to modify the firmware_class state as we move in between states.
- * The firmware_class implements a firmware cache to enable device driver
- * to fetch firmware upon resume before the root filesystem is ready. We
- * disable API calls which do not use the built-in firmware or the firmware
- * cache when we know these calls will not work.
- *
- * The inner logic behind all this is a bit complex so it is worth summarizing
- * the kernel's own suspend/resume process with context and focus on how this
- * can impact the firmware API.
- *
- * First a review on how we go to suspend::
- *
- *	pm_suspend() --> enter_state() -->
- *	sys_sync()
- *	suspend_prepare() -->
- *		__pm_notifier_call_chain(PM_SUSPEND_PREPARE, ...);
- *		suspend_freeze_processes() -->
- *			freeze_processes() -->
- *				__usermodehelper_set_disable_depth(UMH_DISABLED);
- *				freeze all tasks ...
- *			freeze_kernel_threads()
- *	suspend_devices_and_enter() -->
- *		dpm_suspend_start() -->
- *				dpm_prepare()
- *				dpm_suspend()
- *		suspend_enter()  -->
- *			platform_suspend_prepare()
- *			dpm_suspend_late()
- *			freeze_enter()
- *			syscore_suspend()
- *
- * When we resume we bail out of a loop from suspend_devices_and_enter() and
- * unwind back out to the caller enter_state() where we were before as follows::
- *
- * 	enter_state() -->
- *	suspend_devices_and_enter() --> (bail from loop)
- *		dpm_resume_end() -->
- *			dpm_resume()
- *			dpm_complete()
- *	suspend_finish() -->
- *		suspend_thaw_processes() -->
- *			thaw_processes() -->
- *				__usermodehelper_set_disable_depth(UMH_FREEZING);
- *				thaw_workqueues();
- *				thaw all processes ...
- *				usermodehelper_enable();
- *		pm_notifier_call_chain(PM_POST_SUSPEND);
