Subject: [PATCH 2/2] vkd3d-shader/dxil: Use the parser once it is initialized.
That commit message is a fair bit less helpful than it could be. I suppose that's intended to be in contrast to patch 1/2, but looking at the contents of the patch I'd suggest something along the lines of "vkd3d-shader/dxil: Use vkd3d_shader_parser_error() for error reporting.", perhaps with some qualifiers.
