usb: Remove ehci_reset call from ehci_run
Remove the ehci_reset() call done in the ehci_run() routine of the USB EHCI host controller driver and add an ehci_reset() call to the probe processing of all EHCI platform drivers that do not already call ehci_reset(). The call to ehci_reset() from ehci_run() was problematic for several platform drivers, and unnecessary for others. This change moves the decision to call ehci_reset() at driver startup to the platform driver code. Signed-off-by: Geoff Levand <geoff@infradead.org> Acked-by: Alan Stern <stern@rowland.harvard.edu>
