usb: sisusb: remove useless macros and compact the code
Remove macros which are only wrappers around standard operations. When we expand them into code, we see that sisusbcon_memsetw can simply use memset16 and sisusbcon_putcs can just call memcpy. So make the code compact. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
