[PATCH 3/6] can: esd_usb: Use consistent prefixes for macros
From: Frank Jungclaus
Date: Wed May 17 2023 - 15:23:28 EST
Initiated by a comment from Vincent Mailhol add the consistent prefix
ESD_USB_ to all macros defined within esd_usb.c.
For macros specific to esd CAN-USB/2 use ESD_USB_2_ as prefix.
For macros specific to esd CAN-USB/Micro use ESD_USB_M_ as prefix.
