Hi Dan and Pavel,

Sorry for the late reply. A v2 patch series is prepared, in which the
uninit-value bug is fixed by adding error checking and initialization.
In that case, r8712_usbctrl_vendorreq() is not touched any more. So
WDYT to refactor r8712_usbctrl_vendorreq() in another patch with the
code Dan mentioned above and usb_control_msg_{recv,send} suggested by
Pavel? And for now, the patch series is just confined to fixing
uninit-values. The patches will each focus on one thing that is easy
to understand.

thanks,
