From 270d73c1c32c71e215f1c64e70be82063ec65005 Mon Sep 17 00:00:00 2001 From: Chunyan Zhang Date: Thu, 8 Jan 2015 12:01:27 +0800 Subject: [PATCH] irda: Removed all unused timeval variables In the file au1k_ir.c & via-ircc.h, there were two unused definitions of the timeval type members, this commit therefore removes this unneeded code. In other three files, the same problem is the rx_time member is only ever written, never read, so removed it entirely. Signed-off-by: Chunyan Zhang Reviewed-by: Arnd Bergmann Signed-off-by: David S.
