498ff29800 mei: me: release irq in mei_me_pci_resume error path 
commit 283cb234ef95d94c61f59e1cd070cd9499b51292 upstream.

The mei_me_pci_resume doesn't release irq on the error path,
in case mei_start() fails.

Extend the quirk to disable MEI interface on Intel PCH Ignition (IGN)
and SPS firmwares for RPL-S devices. These firmwares do not support
the MEI protocol.

2f79d3d1f7 mei: add device kind to sysfs 
Some of the mei device heads are not generic and have
a specific purpose, we need to announce it to the user space
so it is possible to detect the correct device node via
matching attributes.

Generic heads are marked as 'mei' while special purpose heads
have their own names. Currently we are adding 'itouch' string
for Intel IPTS 1.0, 2.0 devices.

This is done via new sysfs attribute 'kind'.

Commit 261b3e1f2a ("mei: me: store irq number in the hw struct.")
stores the irq number in the hw struct before MSI is enabled.  This
caused a regression for mei_me_synchronize_irq() waiting for the wrong
irq number.  On my laptop this causes a hang on shutdown.  Fix the issue
by storing the irq number after enabling MSI.

cc365dcf0e mei: me: allow runtime pm for platform with D0i3 
>From the pci power documentation:
"The driver itself should not call pm_runtime_allow(), though. Instead,
it should let user space or some platform-specific code do that (user space
can do it via sysfs as stated above)..."

However, the S0ix residency cannot be reached without MEI device getting
into low power state. Hence, for mei devices that support D0i3, it's better
to make runtime power management mandatory and not rely on the system
integration such as udev rules.
This policy cannot be applied globally as some older platforms
were found to have broken power management.
