[PATCH 0/4] usb: initialize debugfs command buffers

[Jiale Yao]

Several USB debugfs write handlers copy user input into uninitialized stack
buffers and then compare fixed command lengths. A short write that matches a
command prefix can therefore make strncmp() inspect uninitialized bytes.

Zero-initialize the affected command buffers so every copied input is
terminated and the comparisons do not depend on stale stack contents.
