From aa15c0a347be6d5d16c557ed5b6b72345be48bdd Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 26 Sep 2009 13:29:35 -0300 Subject: [PATCH] V4L/DVB (13042): Add NEC protocol to firmware v1.2 handler Currently, dvb_usb_dib0700_ir_proto is supported only with firmwares older than 1.2. Adds support for it also with the newer firmware. This is needed in order to support PixelView SBTVD IR.
