[PATCH] dvb: ttpci: fix error handling for firmware communication
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 Signed-off-by: Wolfgang Rohdewald <wolfgang@rohdewald.de> Signed-off-by: Johannes Stezenbach <js@linuxtv.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
