From d09ac610eaaa0b3b29c3ac6c4e107cb1dbd4a356 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 1 Jan 2018 21:32:02 -0800 Subject: Input: hp_sdc - convert to ktime_get() This gets rid of the deprecated do_gettimeofday() call in favor of ktime_get(), which is also more reliable as it uses monotonic times. The code now gets a bit simpler.
