Subject: [PATCH RFC] ARM: imx8: fix discrepancy between comment and code
Date: Fri, 31 May 2019 09:41:02 +0200	[thread overview]
Message-ID: <20190531074102.28035-1-a.fatoum@pengutronix.de> (raw)

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.
