Subject: [PATCH] EDAC: skx_common: downgrade message importance on missing PCI
device
mainline inclusion
from mainline-v5.6-rc4
commit 854bb48018d5da261d438b2232fa683bdb553979
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5Q0UG
CVE: NA
---------------------------
Both skx_edac and i10nm_edac drivers are loaded based on the matching CPU being
available which leads the module to be automatically loaded in virtual machines
as well. That will fail due the missing PCI devices. In both drivers the first
function to make use of the PCI devices is skx_get_hi_lo() will simply print
EDAC skx: Can't get tolm/tohm
for each CPU core, which is noisy. This patch makes it a debug message.
