Subject: [PATCH v1] RISC-V: hwprobe: sort EXT_KEY()s in hwprobe_isa_ext0() alphabetically
From: Conor Dooley <conor.dooley@...rochip.com>
Currently the entries appear to be in a random order (although according
to Palmer he has tried to sort them by key value) which makes it harder
to find entries in a growing list, and more likely to have conflicts as
all patches are adding to the end of the list. Sort them alphabetically
instead.
