[PATCH 1/4] ide: don't set hwif->dma_ops in init_dma() method

[Sergei Shtylyov <sshtylyov@ru.mvista.com>]

Replace setting of 'hwif->dma_ops' in the 'alim16x3' and 'palm_bk3710' drivers'
init_dma() methods with initializing the corresponding member of their 'struct
ide_port_info' instances and remove such setting from the 'hpt366' driver that
just doesn't use 'sff_dma_ops'. Along with some code save, this prepares us for
the next patch...

Here are the unfortunate series of patches that hadn't gotten into 2.6.28 --
I decided not to leave it to the next year despite an extreme overload I had
during the past several months... :-)
The patch is atop of the current pata-2.6 series...
