Subject: USB: message: cleanup min_t() cast in usb_sg_init()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=edb2b255a0bebac5aeb17c7613aeb76ba4e6c63c;p=openwrt%2Fstaging%2Fblogic.git

USB: message: cleanup min_t() cast in usb_sg_init()

"length" is type size_t so the cast to unsigned int truncates the
upper bytes.  This isn't an issue in real life (I've checked the
callers) but it's a bit messy.
