Subject: [media] nuvoton-cir: improve buffer parsing responsiveness Author: Jarod Wilson <[email protected]> Date: Tue Nov 9 18:11:04 2010 -0300 Rather than waiting for trigger bits, the formula for which was slightly messy, and apparently, not actually 100% complete for some remotes, just call ir_raw_event_handle whenever we finish parsing a chunk of data from the rx fifo, similar to mceusb, as well as whenever we see an 'end of signal data' 0x80 packet.
