Subject: [PATCH RFC 01/18] staging: vchiq_core: rework vchiq_get_config
Date: Fri, 26 Oct 2018 15:47:56 +0200 [thread overview]
Message-ID: <20181026134813.7775-2-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20181026134813.7775-1-nsaenzjulienne@suse.de>
The function is overly complicated for what it's ultimately achieving.
It's simply filling up a structure.
