*/*: use $(...) notation instead of legacy backticked `...`
This has been done automatically with shellcheck:
shellcheck -s ash -i SC2006 -f diff -- */*/APKBUILD | git apply
This has only been applied to APKBUILD files. More would possible but may not be that reliable:
shellcheck -s ash -i SC2006 -f diff -- */*/*.initd */*/*.confd $(grep "#!/bin/sh" * -rl | grep -v .patch | grep -v README) | git apply
