From 78e41c16c0b5d47415f01ead3a3730d5b9a6a52c Mon Sep 17 00:00:00 2001 From: Daniel Scheller Date: Mon, 11 Dec 2017 15:12:49 -0500 Subject: [PATCH] media: ddbridge: stv09xx: detach frontends on lnb failure While the failure handling in dvb_input_attach() has been improved lately so any tuner failure won't result in demod driver modules with a usecount > 0 anymore (thus requiring rmmod -f), there's still an issue with stv090x and stv0910 based tuner modules, in that LNB driver attach failures leave an attached demod frontend driver behind which have a usecount of > 0 in this failure case, due to them not being detached/ released. Fix this by detaching the demod frontends if the LNB driver fails. Richard tested and verified the changes with STV0910 hardware, thus adding his Tested-by.
