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.
