Subject:    [PATCH 1/6] can: peak_usb: rename a callback to a more explicit name
From:       Stephane Grosjean <s.grosjean () peak-system ! com>

[Download RAW message or body]

The so-called "device id" is in fact a value defined by the user.
Therefore, in order not to confuse it with the device id used by the USB,
the functions for reading this user-defined value are renamed.
