Subject: [PATCH] irqchip/irq-mvebu-sei: Fix a NULL vs IS_ERR() bug in probe
Date: Sat, 13 Oct 2018 10:22:46 +0000	[thread overview]
Message-ID: <20181013102246.GD16086@mwanda> (raw)

The devm_ioremap_resource() function never returns NULL, it returns
error pointers.

Fixes: 61ce8d8d8a81 ("irqchip/irq-mvebu-sei: Add new driver for Marvell SEI")
