Subject: intel: Don't complain when getparam fails due to a missing param.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f6ca4a304bf920ea6913b08638fb8eb3e020d446;p=mesa.git

intel: Don't complain when getparam fails due to a missing param.

This is an expected behavior when we're testing for the presence of
new kernel features.
