usb: gadget: s3c-hsudc: Use struct_size() in devm_kzalloc()

Browse source

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows
that, in the worse scenario, could lead to heap overflows.

This code was detected with the help of Coccinelle and, audited and
fixed manually.
