From a1038ee8ca9f857d4d2e809a02bfe69ecb085b25 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Wed, 8 May 2019 11:11:53 -0400 Subject: [PATCH] media: smiapp: core: add small range to usleep_range No need for a high-accuracy delay here as long as it is more than 2 milliseconds this should be ok - as it is non-atomic context it will be not be precise 2 milliseconds so giving the hrtimer subsystem 50 microseconds to merge timers and reduce interrupts.
