Subject: intel/compiler: Remove cs_prog_data->threads
X-Git-Tag: upstream/20.1.8~1492
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=db74ad0696d205e0991281bc0e222290ab1addd5;p=platform%2Fupstream%2Fmesa.git

intel/compiler: Remove cs_prog_data->threads

At this point all drivers are doing this math on their own -- since
most of them need to cover the variable group size case, in which at
compile time the group size (and number of threads) is not defined.
