icside: don't use hwif->hwif_data
* Move ecard_set_drvdata() from icside_probe() to icside_register_v{5,6}(), then use state->ioc_base instead of hwif->hwif_data in icside_maskproc() and icside_dma_test_irq(). While at it: * Add sel field to struct icside_state, then use state->{sel,ioc_base} instead of ->{select,config}_data in icside_dma_setup(). There should be no functional changes caused by this patch. Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
