Vincent Mailhol says:

====================
This series contains two clean up patches toward struct es58x_device
of the CAN etas_es58x driver. The first one removes the field
rx_max_packet_size which value can actually be retrieved from the
helper function usb_maxpacket(). The second one fixes the signedness
of the TX and RX pipes.

No functional changes.
