| Subject: ipr: Clear interrupt on croc/crocodile when running with LSI |
| |
| From: Brian King <brking@linux.vnet.ibm.com> |
| |
| 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. |
