4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Daniel Drake <[email protected]> commit 7e6fc2f50a3197d0e82d1c0e86282976c9e6c8a4 upstream. The outb() function takes parameters value and port, in that order. Fix the parameters used in the kalsr i8254 fallback code.
