From cac821d2ea72fbefb16e8af1e192ec70aae29afe Mon Sep 17 00:00:00 2001 From: Brad Love Date: Thu, 30 May 2019 16:32:25 -0400 Subject: [PATCH] media: pvrusb2: Add multiple dvb frontend support All changes are equivalent and backwards compatible. All current devices have been changed to use fe[0] Code has been added to dvb init to support cleanup after failure. Multiple frontends are required by Hauppauge HVR-1975, which is in a later commit.
