Subject: i915g: Correct PIPE_SHADER_CAP_MAX_TEMPS.
X-Git-Tag: upstream/22.3.5~19022
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8ebd0f8317c77bfe0d28923d7f4d66e953e5da01;p=platform%2Fupstream%2Fmesa.git

i915g: Correct PIPE_SHADER_CAP_MAX_TEMPS.

This is the value that i915c reported, too, and is required for ARB_fp.
