Subject: mesa: Make numSamples an unsigned int
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fef4b16523dea0be0de748fcab7e6367ed8e9542;p=mesa.git

mesa: Make numSamples an unsigned int

As a followup to the previous patch propagate the change of numSamples
from int to unsigned to gl_config::samples and consequently fix some
-Wsign-compare warnings.
