From 6cdeaed3b1420bd2569891be0c4123ff59628e9e Mon Sep 17 00:00:00 2001 From: Wolfgang Rohdewald Date: Tue, 28 Nov 2017 06:33:52 -0500 Subject: [PATCH] media: dvb_usb_pctv452e: module refcount changes were unbalanced dvb_frontend will call dvb_detach for: - stb0899_detach in dvb_frontend_release and - stb0899_release in __dvb_frontend_free But we only do dvb_attach(stb0899_attach). Increment the module refcount instead.
