[DVB patch 24/51] ttpci: fix error handling for firmware communication
From: Johannes Stezenbach
Date: Mon Jun 27 2005 - 08:10:16 EST
From: Wolfgang Rohdewald <wolfgang@xxxxxxxxxxxx>
o make sure ERESTARTSYS will be propagated
o ReleaseBitmap: starting with Firmware 261e, also release when
BMP_LOADING
o removes unused #define BMP_LOADINGS
o in many cases changed the return value from -1 to something more
meaningful like ETIMEDOUT, EINVAL
o changed syslog message timeout waiting for COMMAND such that it
indicates what command did not complete
o reduce # of arguments for LoadBitmap and BlitBitmap
o av7110_osd_cmd: remove the out: label
