[SRU][F/linux-firmware][PULL] Missing firmware files, in Ubuntu 20.04 LTS, for initramfs, when it loads i915 (LP: #1939986)

[Juerg Haefliger]

BugLink: https://bugs.launchpad.net/bugs/1939986

[ Impact ]

The i915 driver in Focal HWE kernels (currently 5.11 and 5.13) needs new firmware blobs. Without them, some users reported display/audio issues when installing said kernel.


[ Test Case ]

1) Install linux-generic-hwe-20.04
2) echo 'i915' >> /etc/initramfs-tools/modules
3) update-initramfs -u

Which leads to multiple warnings:
W: Possible missing firmware <foo> for module i915


[Fix ] 

Add missing firmware blobs from upstream linux-firmware.


[ Where Problems Could Occur ]

New closed-source firmware binaries, would could possibly go wrong? No display with i915, kernel crashes.
