+Subject: [PATCH] uvcgadget: Use g_path_get_basename instead of libc basename
+
+Musl does not implement GNU basename and have fixed a bug where the
+prototype was leaked into string.h [1], which resullts in compile errors
+with GCC-14 and Clang-17+
+
+| sys/uvcgadget/configfs.c:262:21: error: call to undeclared function 'basename'
+ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
+|   262 |     const char *v = basename (globbuf.gl_pathv[i]);
+|       |                     ^
+
+Use glib function instead makes it portable across musl and glibc on
+linux
