V4L/DVB: cx23885, cx25840: Report IR max pulse width regardless of mod/demod use
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. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
