[DVB patch 28/51] ttpci: more error handling for firmware communication
From: Johannes Stezenbach
Date: Mon Jun 27 2005 - 08:32:37 EST
From: Wolfgang Rohdewald <wolfgang@xxxxxxxxxxxx>
o propagate more errors back to caller or log them, mainly in
av7110.c and av7110_av.c
o fix error message in StartHWFilter
o do not StopHWFilter for handle 0xffff
