From: Brian King <redacted> This patch has been added to the 3.12 stable tree. If you have any objections, please let us 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.
