We want both chagallwifi and chagalllte to be able to depend on
firmware-samsung-chagall, for both their downstream and mainline
kernel variants.
Previously we used install_if like:
install_if="device-samsung-chagallwifi-kernel-mainline"
which will only work for chagallwifi and not chagalllte. Instead we
add two nonfree subpackages to the device packages that install_if's
depending on kernel choice.
mesa-dri-swrast no longer exists and just installs,
mesa-dri-gallium. However, this might not always be the case, so
let's change it before it causes any issues.
[ci:ignore-count]
[ci:skip-build]
At the moment we have Contributor: lines on some packages (but not all of them),
but often they don't represent the actual contributors to the package very well.
E.g. when we added them retroactively to the device packages we only added
the initial contributor (which isn't necessarily the person
who made most of the work for a device...)
The Git history is the most representative source for figuring out
who contributed to a package, so there is no reason to duplicate that
into the APKBUILD.
[skip ci]: way too many packages
