V4L/DVB (13001): Key filter for BeholdTV cards.
When fast push-pull button of remote control we can received incorrect key code 0x00. Key information from IR decoder has ID of remote control 2 bytes, byte of key code and byte of mirror key code. Correct data 0x86 0x6B 0x00 0xFF Wrong data 0x86 0x6B 0x00 0x00 This patch added additional test of mirror byte for filtering. Signed-off-by: Beholder Intl. Ltd.
