[Bug 2007783] [NEW] MIPI kernel drivers fail to work due to I2C conflict

[Derrik Pates]

Public bug reported:

On my Lenovo ThinkPad X1 Nano Gen2 (and apparently some other laptops?),
there is a Lattice Semiconductor I2C firmware update endpoint that
prevents the MIPI camera drivers from communicating and working. After
applying a small patch and building the kernel locally (which blacklists
the Lattice device, which is apparently not actually supported anyway),
I'm able to get the MIPI camera functioning.

** Affects: initramfs-tools (Ubuntu)
