Subject: [PATCH v2 03/12] staging: wilc1000: simplify msgqueue code
Date: Mon,  1 Jun 2015 21:06:36 +0200	[thread overview]
Message-ID: <1433185605-2492600-4-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1433185605-2492600-1-git-send-email-arnd@arndb.de>

The driver contains an abstraction for message queues, with
optional unused features, while the driver requires the main
feature.

This makes the msgqueue code unconditional as it's required
but removes the unused parts.

A later cleanup should remove the entire msgqueue code
and replace it with some normal kernel API.
