From 964481ad0e03c161c395b95c7e53cb6ddfdc4b98 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Tue, 13 Dec 2016 03:34:53 -0200 Subject: [PATCH] [media] m5mols: set usleep_range delta greater 0 This delay is in non-atomic context and it does not seem to be time-critical so relax it to allow the timer subsystem to optimize hrtimers.
