XRRGetProviderInfo: Remove unneeded ProviderInfoExtra
It was always 0, hence caused gcc warnings:
XrrProvider.c: In function ‘XRRGetProviderInfo’:
XrrProvider.c:133:49: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
if (rep.length > INT_MAX >> 2 || rep.length < ProviderInfoExtra >> 2)
^
XrrProvider.c:135:17: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]
if (rep.length < ProviderInfoExtra >> 2)
^
XrrProvider.c:135:5: warning: this condition has identical branches [-Wduplicated-branches]
if (rep.length < ProviderInfoExtra >> 2)
^
