Subject: usb: chipidea: Enable user-space triggered role-switching
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6dbbbccdba6118b30837c42f3d356ecf0aaf4a1f;p=linux.git

usb: chipidea: Enable user-space triggered role-switching

The flag provided by the USB role-switch logic allow_userspace_control
allows user-space to trigger a role-switch. Several other USB controller
drivers already enable this feature. Let's switch it on for the chipidea
core now also.
