mtd: omap2: allow bulding as a module

2013-06-19T15:53:46+00:00

The omap2 nand device driver calls into the the elm code, which can
be a loadable module, and in that case it cannot be built-in itself.
I can see no reason why the omap2 driver cannot also be a module,
so let's make the option "tristate" in Kconfig to fix this allmodconfig
build error:

ERROR: "elm_config" [drivers/mtd/nand/omap2.ko] undefined!
ERROR: "elm_decode_bch_error_page" [drivers/mtd/nand/omap2.ko] undefined!

drivers/mtd/nand: don't check resource with devm_ioremap_resource

2013-05-18T09:55:55+00:00

devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

Pull removal of GENERIC_GPIO from Grant Likely:
 "GENERIC_GPIO now synonymous with GPIOLIB.  There are no longer any
  valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
  is possible to do so which has been causing confusion and breakage.
  This branch does the work to completely eliminate GENERIC_GPIO."

Convert selectors of GENERIC_GPIO to GPIOLIB

2013-04-16T09:47:14+00:00

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on
GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

Since this driver is dt only and denali_nand_dt_ids is always
compiled in, use of of_match_ptr() macro is not necessary.

mtd: denali_dt: Change return value to fix smatch warning

2013-04-05T13:04:20+00:00

platform_get_irq() also returns -ENXIO upon failure.
Use it instead of hardcoded return type.

Fixes the following smatch warning:
drivers/mtd/nand/denali_dt.c:93 denali_dt_probe() info:
why not propagate 'denali->irq' from platform_get_irq() instead of (-6)?
