From 2dd002e928b8b933d1efce04bfebf9ed1adc0541 Mon Sep 17 00:00:00 2001 From: Ahmad Fatoum Date: Fri, 31 May 2019 09:41:02 +0200 Subject: ARM: imx8: fix discrepancy between comment and code The comment speaks of a one second polling timeout, while the polling is indefinite with timeout not accounted for. Thus change the comment to reflect the actual behavior.
