NAME

6       devm_request_resource - request and reserve an I/O or memory resource
7

SYNOPSIS

9       int devm_request_resource(struct device * dev, struct resource * root,
10                                 struct resource * new);
11

ARGUMENTS

13       dev
14           device for which to request the resource
15
16       root
17           root of the resource tree from which to request the resource
18
19       new
20           descriptor of the resource to request
21

DESCRIPTION

23       This is a device-managed version of request_resource. There is usually
24       no need to release resources requested by this function explicitly
25       since that will be taken care of when the device is unbound from its
26       driver. If for some reason the resource needs to be released
27       explicitly, because of ordering issues for example, drivers must call
28       devm_release_resource rather than the regular release_resource.
29
30       When a conflict is detected between any existing resources and the
31       newly requested resource, an error message will be printed.
32
33       Returns 0 on success or a negative error code on failure.
