> Subject: [Intel-wired-lan] [PATCH v2] e1000e: Populate entire
> system_counterval_t in get_time_fn() callback
> 
> get_time_fn() callback implementations are expected to fill out the
> entire system_counterval_t struct as it may be initially
> uninitialized.
> 
> This broke with the removal of convert_art_to_tsc() helper functions
> which left use_nsecs uninitialized.
> 
> Assign the entire struct again.
