From 22184ee779d37f2c64b08ea427d939f0e2d58b37 Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sat, 25 Mar 2006 16:40:16 -0600 Subject: Implement method in pvrusb2 to force the decoder to reset From: Mike Isely This change threads logic through the pvrusb2 to make it possible to command the decoder chip to reset itself. The method is decoder-agnostic; the part of the pvrusb2 which control's that chip's module has to provide the final hook. This just lays the foundation.
