Subject: [media] dib0700: Fix IR keycode handling
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=59aa346009c06c6697e9db008e67e4ff8c205091;p=linux-beck.git

[media] dib0700: Fix IR keycode handling

Fixes Fedora 14 bug: https://bugzilla.redhat.com/show_bug.cgi?id=667157

There are a few bugs at the code that generates the scancode at dib0700:
	- RC keycode is wrong (it outputs a 24 bits keycode);
	- NEC extended outputs a keycode that have endiannes issues;
	- keycode tables for NEC extended remotes need to be updated.

The last issue need to be done as we get reports, as we don't have
the complete NEC-extended keycodes at the dibcom table.

This patch fixes the first two issues.
