ide: fix crash at boot with siimage driver
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. [bart: while at it: sil_dma_ops should be const now (pointed out by Sergei)] Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com>, Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
