| |
Over-current reporting isn't supported on some platforms such as bcm63xx. These devices will incorrectly report over-current if this flag isn't properly activated.
Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com> --- v3: no changes. v2: change flag name and improve documentation as suggested by Alan Stern.
