Hi Marcel Does this v2 patch address the concerns you mentioned in your review of the v1 patch at https://lore.kernel.org/linux-bluetooth/3EA82A93-D167-482D-AAF4-D781B77A4646@xxxxxxxxxxxx/ ? Or can you explain a bit more how I misunderstood your request? This patch correctly documents the strict patterns of dozens or so existing firmware files which this driver can load for each of the hw variants.
