From f8e00d5fa86fbc4462647da162152d4e74db784c Mon Sep 17 00:00:00 2001 From: David Härdeman Date: Thu, 28 Apr 2011 11:14:03 -0300 Subject: [media] rc-core: move timeout and checks to lirc The lirc TX functionality expects the process which writes (TX) data to the lirc dev to sleep until the actual data has been transmitted by the hardware. Since the same timeout calculation is duplicated in more than one driver (and would have to be duplicated in even more drivers as they gain TX support), it makes sense to move this timeout calculation to the lirc layer instead. At the same time, centralize some of the sanity checks.
