From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 3f6f6343a29d9ea7429306b83b18e66dc1331d5c upstream.
This code is using the wrong sizeof() so it does not allocate enough
memory. It allocates 32 bytes but 72 are required. That will lead to
memory corruption.
Fixes: ae07809255d3 ("usb: mtu3: add debugfs interface files")
