Subject: USB: usbfs: struct async is a fixed size structure
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=dd95b814115e45e0bf800f2950b9941c86e68172;p=deliverable%2Flinux.git

USB: usbfs: struct async is a fixed size structure

The ISO descriptors are allocated separately in proc_submiturb for a fetch
from user mode, then tucked at the end of URB. This seems like a dead code.
