commit 0be1a655fe68c8e6dcadbcbddb69cf2fb29881f5 upstream. can_restart() expects CMD_START_CHIP to set the error state to ERROR_ACTIVE as it calls netif_carrier_on() immediately afterwards. Otherwise the user may immediately trigger restart again and hit a BUG_ON() in can_restart(). Fix kvaser_usb_leaf set_mode(CMD_START_CHIP) to set the expected state.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
