usb: gadget: sdp: fix pointer cast warnings for 64bit archs
The SDP protocol contains multiple 32bit pointers. Add a helper function
to get a valid pointer from these values and use it.
This fixes the following warnings:
drivers/usb/gadget/f_sdp.c: In function ‘sdp_rx_data_complete’:
drivers/usb/gadget/f_sdp.c:347:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
memcpy((void *)sdp->dnl_address, req->buf + 1, datalen);
^
drivers/usb/gadget/f_sdp.c: In function ‘sdp_jump_imxheader’:
drivers/usb/gadget/f_sdp.c:625:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
entry = (void *)headerv2->entry;
^
drivers/usb/gadget/f_sdp.c: In function ‘sdp_handle_in_ep’:
drivers/usb/gadget/f_sdp.c:668:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
memcpy(&data[1], (void *)sdp_func->dnl_address, datalen);
^
drivers/usb/gadget/f_sdp.c:679:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
status = sdp_jump_imxheader((void *)sdp_func->jmp_address);
^
