From e4d75d07cba4e4d7a8ae98dfc8815dcfe9425723 Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Fri, 2 Jan 2015 10:56:27 -0300 Subject: [PATCH] lmedm04: Increase Interupt due time to 200 msec commit cfcd7b825892cb498c6bcb13257f2141f7eacb76 upstream. Ocassionally the device fails to report back an interrupt urb status which results in false no lock trigger on the RS2000 demodulator. Increase time from 60 msecs to 200 msecs.
