Hi!

[ Upstream commit c9f86d6ca6b5e23d30d16ade4b9fff5b922a610a ]
The DMI callbacks, used for quirks, currently access the PMC by getting the address a global pmc_dev struct. Instead, have the callbacks set a global quirk specific variable. In probe, after calling dmi_check_system(), pass pmc_dev to a function that will handle each quirk if its variable condition is met. This allows removing the global pmc_dev later.
This does not fix a bug.. it is preparation for further cleanups that are not queued to 5.10 stable. So this should not be in 5.10 either.
Best regards, Pavel
