From: Ying Zhang b40530@freescale.com
Because the function ft_board_setup() delete the USB2 device node, it leads to can't find the device node and hung up.
In fact only P1020RDB needs to delete the USB2 node, this patch fixes this issue.
Signed-off-by: Ying Zhang b40530@freescale.com --- Change from v1: - To define the parameter "err" to eliminate the compiling error.
