Subject: uas: Pack iu struct definitions
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d24354bbf78f9194ec21087130a69b84864e50df;p=openwrt%2Fstaging%2Fblogic.git

uas: Pack iu struct definitions

The iu struct definitions are usb packet definitions, so no alignment should
happen. Notice that assuming 32 bit alignment this does not make any
difference at all.
