Subject: platform/x86: intel_pmc_core: Add an additional parameter to
pmc_core_lpm_display()
Git-commit: 913f984a8347ea967ee9693dfa1e15da78e64661
Patch-mainline: 5.7-rc1
References: jsc#SLE-12699
Add a device pointer of type struct device as an additional parameter to
pmc_core_lpm_display(), so that the driver can re-use it to dump the
debug registers in resume for an S0ix failure.
