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