From: Andy Walls Date: Sun, 1 Aug 2010 00:57:42 +0000 (-0300) Subject: V4L/DVB: cx23885, cx25840: Report IR max pulse width regardless of mod/demod use X-Git-Tag: Ubuntu-5.2.0-15.16~24077^2~64 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=ceb152add687db152d90ba64b54687b3975963cf;p=mirror_ubuntu-eoan-kernel.git 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.
