      c->oobbuf hasn't been kmalloced in jffs2_dataflash_setup, so
there is no need to free it.

      mtd: cmdlinepart: convert printk() to pr_*() · ecb43e0a
      由 Brian Norris 提交于 
      This driver uses some custom macros for printing. Let's use the standard
pr_fmt()/pr_{err,warn}().

      mtd: cmdlinepart: allow small partitions · d855d23b
      由 Brian Norris 提交于 
      I'm not sure why we have a PAGE_SIZE restriction on this partition
parser.

If we really wanted the restriction, I would expect it to be a
restriction for *all* parsers, so we'd move it to the MTD core

At any rate, while small partitions may not be useful (they'll often be
smaller than the eraseblock size and therefore can only be used
read-only), they still have use as a read-only partition.

This restriction is especially annoying because it aborts the entire
MTD's cmdline parsing, leaving it unpartitioned.

So, let's kill the restriction and only check for zero-sized partitions,
which I expect we don't want to allow.

      mtd: nand: pxa3xx-nand: prevent DFI bus lockup on removal · e971affa
      由 Robert Jarzmik 提交于 
      After the conversion of pxa architecture to common clock framework, the
NAND clock can be disabled on driver exit.

In this case, it happens that if the driver used the NAND and set the
DFI arbitration bit, the next access to a static memory controller area,
such as an ethernet card, will stall the system bus, and the core will
be stalled forever.

This is especially true on pxa31x SoCs, where the NDCR was augmented
with a new bit to prevent this lockups by giving full ownership of the
DFI arbiter to the SMC, in change SCr#6.

Fix this by clearing the DFI arbritration bit in driver exit. This
effectively prevents a lockup on zylonite when removing pxa3xx-nand
module, and using ethernet afterwards.
