Subject: [PATCH 14/30] mci: imx-esdhc: drop one extra read of SDHCI_INT_STATUS
Date: Mon,  5 May 2025 14:06:17 +0200	[thread overview]
Message-ID: <20250505120633.3717186-15-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20250505120633.3717186-1-a.fatoum@pengutronix.de>

Our new esdhc_poll implementation stores the register value read for
later use, so make use of it instead of reading the same register again
after the break condition has been triggered.
