Subject: [PATCH] of: Move the request module helper logic to module.c
|
|
|
|
Depending on device.c for pure OF handling is considered
|
|
backwards. Let's extract the content of of_device_request_module() to
|
|
have the real logic under module.c.
|
|
|
|
The next step will be to convert users of of_device_request_module() to
|
|
use the new helper.
