Subject: of: reserved_mem: Add missing IORESOURCE_MEM flag on resources
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=aea70964b5a7ca491a3701f2dde6c9d05d51878d;p=users%2Fjedix%2Flinux-maple.git

of: reserved_mem: Add missing IORESOURCE_MEM flag on resources

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"')
