[DVB patch 37/37] budget-av: CI fixes
From: Johannes Stezenbach
Date: Sun May 08 2005 - 14:59:11 EST
- remove enable_ci, ci interface is assumed to be present if the saa7113
is not found.
- reduce the delay when checking for saa7113
- clean up the cam reset according to specifications
- turn off Vcc to the cam slot if cam is removed or fails reset
- remove cam reset in ciintf_init
- clean up printks (KERN_)
- move gpio setting into saa7113_init
- clean up unreadable frontend_init
(Kenneth Aafloy)
