usb: hub: Prevent hub autosuspend if usbcore.autosuspend is -1
If user specifies that USB autosuspend must be disabled by module parameter "usbcore.autosuspend=-1" then we must prevent autosuspend of USB hub devices as well. commit 596d789a introduced in v3.8 changed the original behaivour and stopped respecting the usbcore.autosuspend parameter for hubs. Fixes: 596d789a "USB: set hub's default autosuspend delay as 0" Cc: [3.8+] <stable@vger.kernel.org> Signed-off-by: NRoger Quadros <rogerq@ti.com> Tested-by: NMichael Welling <mwelling@emacinc.com> Acked-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>
