Subject: [PATCH RFC 09/18] staging: vchiq_core: do not initialize semaphores twice
Date: Fri, 26 Oct 2018 15:48:04 +0200	[thread overview]
Message-ID: <20181026134813.7775-10-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20181026134813.7775-1-nsaenzjulienne@suse.de>

vchiq_init_state() initialises a series of semaphores to then call
remote_event_create() on the same semaphores, which initializes them
again.
