Subject: [PATCH] of: reserved_mem: Add missing IORESOURCE_MEM flag on resources
Date: Wed, 20 Aug 2025 14:28:04 -0500 [thread overview]
Message-ID: <20250820192805.565568-1-robh@kernel.org> (raw)
Commit f4fcfdda2fd8 ('of: reserved_mem: Add functions to parse
"memory-region"') failed to set IORESOURCE_MEM flag on the resources.
The result is functions such as devm_ioremap_resource_wc() will fail.
Add the missing flag.
Fixes: f4fcfdda2fd8 ('of: reserved_mem: Add functions to parse "memory-region"')
