From a72c57d78b754f23b050ceb43b2209fce7064cb5 Mon Sep 17 00:00:00 2001 From: Doug Smythies Date: Wed, 30 Jan 2019 08:28:22 -0800 Subject: [PATCH 0769/2944] cpuidle: poll_state: Fix default time limit commit 1617971c6616c87185cbc78fa1a86dfc70dd16b6 upstream The default time is declared in units of microsecnds, but is used as nanoseconds, resulting in significant accounting errors for idle state 0 time when all idle states deeper than 0 are disabled. Under these unusual conditions, we don't really care about the poll time limit anyhow.
