In the function rt2500usb_register_read(_lock), reg is uninitialized
in some situation. Then KMSAN reports uninit-value at its first memory
access. To fix this issue, initialize reg with zero in the function
rt2500usb_register_read and rt2500usb_register_read_lock
BUG: KMSAN: uninit-value in rt250

In the function rt2500usb_register_read(_lock), reg is uninitialized
in some situation. Then KMSAN reports uninit-value at its first memory
access. To fix this issue, add one reg initialization in the function
rt2500usb_register_read and rt2500usb_register_read_lock
BUG: KMSAN: uninit-value in rt2
