Subject: [PATCH] USB: bcma: make helper creating platform dev more generic
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
Having "bool ohci" argument in bcma_hcd_create_pdev function limited it
|
|
to support two cases only (OHCI and EHCI) and put too much logic in it.
|
|
Lets make caller pass all required data. This adds few extra arguments
|
|
to the function call but will allow us to reuse this code and handle
|
|
more cases in the future (e.g. add XHCI support).
