Fix checkpatch.pl bugs ... mostly return-with-parens. And also fix some whitespace bugs, one of which was reported by checkpatch (bad indentation). Signed-off-by:

Update more of the RX and TX buffer descriptor (BD) handling to properly distinguish between __iomem pointers and normal data memory address space, getting rid of 32 "cast removes address space of expression" messages. This patch doesn't resolve all the issues sparse reports. In fact there are now 48 new "dereference of noderef expression" messages. They mean that a patch is needed to convert BD member accessors to use readl/writel calls. Plus, there are several related issues that sparse won't warn about. The initial i/o space addresses -- SRAM used for BDs, and controller registers -- should come from ioremap. Reverse mappings shouldn't usually be needed, and if they are they should avoid io_v2p() and virt_to_phys() calls. And the need to use casts so often is wrong, especially with __force annotations.

Fix about half the warnings from "make C=1" (sparse), and start on the __iomem issues associated with the CPPI buffer descriptor data. All of the remaining warnings come from address space issues. For this driver, fixing all those issues will be quite messy. One of these warnings highlighted minor goofiness in how the module infrastructure was used; fix that too. Signed-off-by:

Do spinlock initialization during davinci_emac::probe(), when the lock is allocated, not each time it's opened. That's the correct place to do such work. More significantly, fix a bug: one of the three spinlocks was never getting initialized, preventing the system from booting in some cases (e.g. running with lockdep). Signed-off-by:

NAND devices can't be hotpluggable. We can use that to shrink code size a bit by using platform_driver_probe(). Signed-off-by:Felipe Balbi <felipe.balbi@nokia.com>

This shrinks the object size of davinci_mmc by about a quarter, ripping out stuff that was issuing all kinds of commands behind the back of the MMC core (evidently for card detect purposes). That's stuff that needs to be ripped out before this driver can go into mainline, obviously; good to remove it ASAP. This has one immediate positive effect: cards which previously could not be enumerated on a dm355evm can now enumerate! (After disabling DMA, for now.) Which in turn let me boot a rootfs from an SD card ... There still seems to be state kept around after card removal, which prevents a second card from enumerating after removing the first one. Also, the MMC core failed when enumerating an MMC card; odd! (Plus fix two broken debug messages: voltages use a bitmask, and newlines don't belong in the *middle* of messages.) Signed-off-by:

Cleanup the way the memory regions are intialised and removes the hard-coded offsets used for EMAC internal modules (MDIO, Control RAM, EMAC wrapper) i.e the assumption that all modules are at fixed offset from the EMAC "base". Also removes the hard coded values for the RAM size, number of transmit and receive buffer descriptors, instead gets the info from the driver structure. Signed-off-by:
