Subject: [PATCH RESEND 1/7] [media] media: introduce MEDIA_REVISION macro
Date: Wed, 21 Jun 2017 10:08:06 +0200 [thread overview]
Message-ID: <20170621080812.6817-2-jthumshirn@suse.de> (raw)
In-Reply-To: <20170621080812.6817-1-jthumshirn@suse.de>
Currently the media code abuses the KERNEL_VERSION macro to encode a
version triplet.
Introduce a MEDIA_REVISION macro to get rid of the confusing and
creative KERNEL_VERSION usage in the media subsystem.
