Subject: V4L/DVB: cx23885, cx25840: Report IR max pulse width regardless of mod/demod use Author: Andy Walls <awa...@md.metrocast.net> Date: Sat Jul 31 21:57:42 2010 -0300 Compute and report the maximum IR pulse measurment width, even if we are set to perform carrier modulation or demodulation and the number is fixed by the carrier freq.
