From: Brian King <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 54e430bbd490e18ab116afa4cd90dcc45787b3df upstream. If we fall back to using LSI on the Croc or Crocodile chip we need to clear the interrupt so we don't hang the system.
