Bug Description
[SRU Justification]
[Impact]
Some AMD platforms might not have sensor reported from MP2 controller,
and that fails device init.
[Fix]
Two commits targeting v6.1 release in mainline kernel.
[Test Case]
On such platforms, driver loading should be bailed out with:
$ sudo dmesg | grep amd_sfh1_
[ 1.204896] pcie_mp2_amd 0000:62:00.7: amd_sfh1_
[Where problems could occur]
This skips driver loading against ineffective hardware only.
[Other Info]
While this targets oem-6.0 and above, and is already in mainline
v6.1-rc1, only oem-6.0 is nominated for fix.
========== original bug report ==========
Fix amd_sfh to make each sensor with proper initialization & resource allocation during MP2 loaded.
To be in v6.1
