| |
Move the check to whether this is a UV system that needs initialization from is_uv_system() to the internal uv_system_init() function. This is because on a UV system without a HUB the is_uv_system() returns false. But we still need some specific UV system initialization. See the uv_system_init() for change to a quick check if UV is applicable. This change should not increase overhead since is_uv_system() also called into this same area.
