Subject: usb: re-use existing values, don't re-determine bus and device address
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=6f63b1ee67ef9a8d9511aec9bac5f9d84c21356d;p=libsigrok.git

usb: re-use existing values, don't re-determine bus and device address

Avoid repeated libusb bus number and device address retrieval operations,
instead use variables where the information previously got stored to.
