/**
* disable_rpm_wakeref_asserts - disable the RPM assert checks

*
* This function disable asserts that check if we hold an RPM wakelock
* reference, while keeping the device-not-suspended checks still enabled.
* It's meant to be used only in special circumstances where our rule about
* the wakelock refcount wrt. the device power state doesn't hold. According
* to this rule at any point where we access the HW or want to keep the HW in
* an active state we must hold an RPM wakelock reference acquired via one of
* the intel_runtime_pm_get() helpers. Currently there are a few special spots
* where this rule doesn't hold: the IRQ and suspend/resume handlers, the
* forcewake release timer, and the GPU RPS and hangcheck works. All other
* users should avoid using this function.
*
* Any calls to this function must have a symmetric call to
* enable_rpm_wakeref_asserts().
