> Subject: [PATCH] drivers/net: fix FW version get
> 
> Fixes a few different things:
> * Remove 'fw_version' NULL checks, it is allowed if the 'fw_size' is
>   zero, 'fw_version' being NULL but 'fw_size' not zero condition checked
>   in ethdev layer
> * Be sure required buffer size is returned if provided one is not big
>   enough, instead of returning success (0)
> * Document in doxygen comment the '-EINVAL' is a valid return type
> * Take into account that 'snprintf' can return negative value
> * Cast length to 'size_t' to compare it with 'fw_size'
