There are a lot of config changes performed by the first patch:
25696931fa618 ("UBUNTU: [Packaging] linux-azure: Add basic packaging
support for arm64")
Some may not be needed, for example:
CONFIG_HID_PLAYSTATION=m
Is this because of changes in the the base Impish kernel?
This first patch does not apply to the master branch in Impish, but does
apply cleanly to the master-next branch so:
