[SRU] [H/U/OEM-5.10] [PATCH 0/1] Fix kernel panic on non-PCI efifb

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1922403

[Impact]
Kernel panic at boot time on RPi4 UEFI and Hyper-V.

[Fix]
efifb isn't neccessarily a PCI device, so check that before using it.

[Test]
Boot Hirsute kernel on Hyper-V.
With the fix applied, no more kernel panic at boot.

[Where problems could occur]
Nothing really. The NULL check should've done in the first place.
