[SRU] [OEM-X] [PATCH 0/1] Fix "Unable to handle kernel paging request" in AMD MP2 driver

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1775152

[Impact]
Touchpad doesn't work after boot. Roughly 1/10 fail rate.

[Test]
With the patch, I no longer see the issue in 30 times reboot.

[Fix]
Factor out the pointer in the union, so the pointer value won't get changed by other union member.

[Regression Potential]
Low. It's specific to a single driver, which only enabled in OEM-A kernel.
