Subject: bindings: cxx: make bitset_cmp::operator() const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c34d74a7e66cbea0cf1a8593a93e5928a3c05661;p=qemu-gpiodev%2Flibgpiod.git

bindings: cxx: make bitset_cmp::operator() const

This fixes build problems with clang and libc++ and such constness is
now required by C++17 (see https://cplusplus.github.io/LWG/issue2542).
