Subject: [PATCH] irqchip/mvebu-gicp: Fix an IS_ERR() vs NULL check in probe()
Date: Tue, 19 Aug 2025 12:40:02 +0300 [thread overview]
Message-ID: <aKRGcgMeaXm2TMIC@stanley.mountain> (raw)
The ioremap() function never returns error pointers, it returns NULL
on error. Fix the checking to match.
Fixes: 3c3d7dbab2c7 ("irqchip/mvebu-gicp: Clear pending interrupts on init")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>
