Subject[PATCH 110/141] V4L/DVB (3378): Restore power on defaults of tda9887 after tda8290 probe
Date
From: Hartmut Hackmann <hartmut.hackmann@t-online.de>
Date: 1141009751 -0300

The probing code for tda8290 changes the state of the tda9887 GP ports.
The patch assumes that if probing for tda8290 failed, this must be a
tda9887 and restores its power on defaults.
This should solve the module load order issue with some pinnacle cards.
