Subject: [PATCH v2 0/2] staging: rtl8712: fix uninit-value 'data' and 'mac'

This is a v2 patch to fix KMSAN: uninit-value in r871xu_drv_init,
https://syzkaller.appspot.com/bug?id=3cd92b1d85428b128503bfa7a250294c9ae00bd8
Previous version and discussion could be seen here:

Changelog v1->v2:
- Split to two patches.
- Add kmsan reports.
- Fix uninit-value 'data' by adding error checking and initialization
rather than changing logic of r8712_usbctrl_vendorreq().
