Hi,
don't know if this is intended. In 4.15.2 i have:

dmesg:
intel_pmc_core 0000:00:1f.2: enabling device (0000 -> 0002)

lspci:
00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev
21)
Subsystem: Intel Corporation Sunrise Point-LP PMC
Control: I/O- Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop-
ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR- INTx-
Region 0: Memory at dff00000 (32-bit, non-prefetchable)
[size=16K]
Kernel driver in use: intel_pmc_core


in 4.16.0-rc1 this becomes
dmesg:
intel_pmc_core: initialized

lspci:
00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev
21)
Subsystem: Intel Corporation Sunrise Point-LP PMC
