Subject: [PATCH 11/12] mci: imx-esdhc: remove misleading NULL check for cmd pointer
Date: Mon, 16 Feb 2026 09:42:27 +0100 [thread overview]
Message-ID: <20260216084253.3547270-11-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20260216084253.3547270-1-a.fatoum@pengutronix.de>
The ternary `cmd ? cmd->cmdidx : 0` suggests cmd can be NULL, but all
callers always pass a valid pointer and sdhci_set_cmd_xfer_mode()
unconditionally dereferences cmd a few lines later. Remove the
unnecessary guard to make the code consistent.
Reported-by: GCC 14.2 -fanalyzer
