From cac2b0eb18e140e2f63146d0f97691e9238570b6 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Tue, 22 Apr 2008 14:46:04 -0300 Subject: [PATCH] V4L/DVB (7379): tuner: prevent instance sharing if i2c adapter is NULL We currently do not have a method to enable instance staring if i2c adapter is NULL, in the cases of dvb demods that write to the tuner directly using calc_regs. Prevent possible wrong instance sharing for these cases until a better solution can be found.
