Subject[PATCH 3.12 044/100] ipr: Clear interrupt on croc/crocodile when running with LSI
Date
From: Brian King <brking@linux.vnet.ibm.com>

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.
