From 7b3aa7146eeed0f2356a92c0edf5e5c829121070 Mon Sep 17 00:00:00 2001 From: Sean Young Date: Wed, 13 Dec 2017 16:17:44 -0500 Subject: [PATCH] media: lirc: no need to recalculate duration This is code existed for when drivers would send less than the whole buffer; no driver does this any more, so this is redundant. Drivers should return -EINVAL if they cannot send the entire buffer.
