Subject: [PATCH 2/4] pvrusb2: Add multiple dvb frontend support
Date: Thu, 20 Dec 2018 15:57:09 -0600	[thread overview]
Message-ID: <1545343031-20935-3-git-send-email-brad@nextdimension.cc> (raw)
In-Reply-To: <1545343031-20935-1-git-send-email-brad@nextdimension.cc>

All changes are equivalent and backwards compatible.
All current devices have been changed to use fe[0]
Cleanup has been added to dvb init to support cleanup after failure.
