[libvirt] [PATCH] virkeyfile: fix compilation error with clang
Clang complains about condition being always true:
src/util/virkeyfile.c:113:23: error: result of comparison of constant 128 with expression
of type 'const char' is always true
[-Werror,-Wtautological-constant-out-of-range-compare]
while (!IS_EOF && IS_ASCII(CUR) && CUR != ']')
^~~~~~~~~~~~~
src/util/virkeyfile.c:80:26: note: expanded from macro 'IS_ASCII'
~~~ ^ ~~~
