Subject: [PATCH] power: reset: xgene-reboot: Fix a NULL vs IS_ERR() test
Date: Tue, 20 Feb 2024 12:02:22 +0300 [thread overview]
Message-ID: <fe1b90d0-7234-4e03-accc-69a119f6a7eb@moroto.mountain> (raw)
The devm_platform_ioremap_resource() function returns error points. It
never returns NULL. Update the check accordingly.
Fixes: 7ddfd33c6ee5 ("power: reset: xgene-reboot: Use devm_platform_ioremap_resource() helper")
