This problem comes when both ehci_hcd and ehci_fsl are built as modules. Till now, only ehci-hcd was build as module, and other drivers were built into it. I tested ehci_fsl as a module with ehci_hcd as build-in.
Now, there are two solutions for this. 1. export each function in ehci_hcd.c 2. I make ehci-fsl.c as built-in
Please suggest.
