commit 84a2302af790d28f5dd7e03620703710300305f1
Author: Krzysztof Hockuba <krz...@it...>
Date: Wed Feb 3 23:01:29 2021 +0100
Fix jtag_usb_location_equal for path members > 9
In case an USB location path contains path members
larger than 9. The string_length variable is regardless
decremented by 2 with assumption that the member is
one digit length. For exmaple 1-12.2 will fail.
This patch uses strlen to calculate
digits in a path member.
