Subject: [PATCH] mfd: pca9450: don't warn if PCA9450_PWRON_STAT is 0
Date: Fri, 3 May 2024 12:15:19 +0200 [thread overview]
Message-ID: <20240503101519.1226971-1-a.fatoum@pengutronix.de> (raw)
The register is zeroed on read, so network booting always prints the
warning that the reset reason is unknown.
Skip the warning in this case.
