+Subject: [PATCH] uvcvideo: Use auto variable to avoid range loop warnings
+
+With c++17 loop range bases are defined where copy is obvious since
+iterator returns a copy and not reference, gcc11 will emit a warning
+about this
+
+uvcvideo.cpp:432:33: error: loop variable 'name' of type 'const string&' {aka 'const std::__cxx11::basic_string<cha
+r>&'} binds to a temporary constructed from type 'const char* const' [-Werror=range-loop-construct]
+|   432 |         for (const std::string &name : { "idVendor", "idProduct" }) {
+|       |                                 ^~~~
+
+Therefore making it explicit is better
