3.13.11.1 -stable review patch. If anyone has any objections, please let me know.
------------------ From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= <[email protected]> commit c7c656226842679bcd9f39dc24441b4ff398a850 upstream. Misplaced parens cause us to totally clobber the CHICKEN_PIPESL_1 registers with 0xffffffff. Move the parens to the correct place to avoid this. In particular this caused bit 30 of said registers to be set, which caused the sprite CSC to produce incorrect results.
