commit 906b268477bc03daaa04f739844c120fe4dbc991 upstream.

kernelci.org reports a warning for this driver, as it copies a local
variable into a 'const char *' string:

    drivers/mtd/maps/pmcmsp-flash.c:149:30: warning: passing argument 1 of 'strncpy' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]

Using kstrndup() simplifies the code and avoids the warning.

commit 656441478ed55d960df5f3ccdf5a0f8c61dfd0b3 upstream.

The commit 7a654172161c ("mtd/ifc: Add support for IFC controller
version 2.0") added support for version 2.0 of the IFC controller.
The version 2.0 controller has the ECC status registers at a different
location to the previous versions.

Correct the fsl_ifc_nand structure so that the ECC status can be read
from the correct location for both version 1.0 and 2.0 of the controller.

Semantics of NR_IRQS is different on machines with SPARSE_IRQ option
disabled or enabled, in the latter case IRQs are allocated starting
at least from the value specified by NR_IRQS and going upwards, so
the check of (irq >= NR_IRQ) to decide about an error code returned by
platform_get_irq() is completely invalid, don't attempt to overrule
irq subsystem in the driver.

The change fixes LPC32xx NAND MLC driver initialization on boot.

Linux should not expect the boot loader to properly configure the

Fix build errors on arch/um, which does not support HAS_IOMEM,
while the oxnas_nand.c driver uses interfaces that are
supplied by HAS_IOMEM.

Remove the usage of modules functions to make this driver compile
again. Otherwise an include of linux/modules.h would be needed.

The xway_nand driver accesses the ltq_ebu_membase symbol which is not
exported. This also should not get exported and we should handle the
EBU interface in a better way later. This quick fix just deactivated
support for building as module.

  sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \

Pull MTD updates from Brian Norris:
 "Nothing enormous here, though notably we have some of the first work
  of a few new maintainers. I think for now I'll still be sending pull
  requests, but that's open to change in the future. Summary:

  Core:

   - dynamic BDI object allocation (resolves some problems when built as
     a module)
   - cleanups in the ooblayout handling

  NAND:

   - new tango NAND controller driver
   - new ox820 NAND controller driver
   - addition of a new full-ID entry in the nand_ids table
   - rework of the s3c240 driver to support DT
   - extension of the nand_sdr_timings to expose tCCS, tPROG and tR
   - addition of a new flag to ask the core to wait for tCCS when
     sending a RNDIN/RNDOUT command
   - addition of a new flag to ask the core to let the controller driver
     send the READ/PROGPAGE command

  Minor fixes/cleanup/cosmetic changes:

   - properly support 512 ECC step size in the sunxi driver
   - improve the error messages in the PXA probe path
   - fix module autoload in the omap2 driver
   - cleanup of several nand drivers to return nand_scan{_tail}() error
     code instead of returning -EIO
   - various cleanups in the denali driver
   - fix an error check in nandsim

  SPI NOR:

   - new flash IDs
   - wait for Spansion flash to be ready after quad-enable
   - error handling fixes for Candence QSPI
   - constify some structures in Freescale QSPI driver"
