Subject: [PATCH 1/1] drivers: usb: core: devio.c: Braces around switch (updated)

Added braces around switch statement as the styleguide tells us.
Indented the switch-block for it and split a function call
(driver->unlocked_ioctl() on line 1876) arguments to several lines to
fit the 80-column convention.
