#regzbot introduced: e5ad96f388b765fe6b52f64f37e910c0ba4f3de7
#regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215467

#regzbot title: Intel TGL notebook no longer enters power states deeper
than PC2

TWIMC: this mail is primarily send for documentation purposes and for
regzbot, my Linux kernel regression tracking bot. These mails usually
contain '#forregzbot' in the subject, to make them easy to spot and filter.

TWIMC: this mail is primarily send for documentation purposes and for
regzbot, my Linux kernel regression tracking bot. These mails usually
contain '#forregzbot' in the subject, to make them easy to spot and filter.

#regzbot backburner: devs need details from intel and a revert would
cause a regression for others:
