Subject: usbcore: fix read of usbdevfs_ctrltransfer fields in proc_control()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c8f2efc8f636506e0f0c2ba4035382076875f0c1;p=openwrt%2Fstaging%2Fblogic.git

usbcore: fix read of usbdevfs_ctrltransfer fields in proc_control()

Urb fields are stored in struct usbdevfs_ctrltransfer in CPU byteorder
and not in little endian, so there is no need to be converted.
This bug was reported by sparse.
