[PATCH] ide: fix crash at boot with siimage driver

From: Benjamin Herrenschmidt
Date: Tue Apr 29 2008 - 00:50:41 EST


Some change to the IDE layer are causing the siimage driver to crash
at boot with a NULL dereference. This is due to the sil_dma_ops not
containing all the necessary pointers. I suppose it used to just
"override" the defaults while now, it needs to contain everything.
