Subject: intel/gen_decoder: Add gen_spec_load_filename() function.
X-Git-Tag: upstream/19.3.0~3855
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=69506cbb7434578eddc08a653fa41a0666abaf0c;p=platform%2Fupstream%2Fmesa.git

intel/gen_decoder: Add gen_spec_load_filename() function.

Refactor the code from gen_spec_load_from_path() into a separate
function, that can be used with a xml file that doesn't fit the genX.xml
filename format.

Will be used soon for implementing unit tests for gen_decoder.
