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 79ad07d45743721010e766e65dc004ad249bd429 upstream.

There is a cut and paste issue here.  The bug is that we are allocating
more memory than necessary for msp_maps.  We should be allocating enough
space for a map_info struct (144 bytes) but we instead allocate enough
for an mtd_info struct (1840 bytes).  It's a small waste.

The other part of this is not harmful but when we allocated msp_flash
then we allocated enough space fro a map_info pointer instead of an
mtd_info pointer.  But since pointers are the same size it works out
fine.

Anyway, I decided to clean up all three allocations a bit to make them
a bit more consistent and clear.

commit e5babdf928e5d0c432a8d4b99f20421ce14d1ab6 upstream.

Since commit bd31b85960a7 (which is in 3.2-rc1) nw_gpio_lock is a raw spinlock
that needs usage of the corresponding raw functions.

This fixes:

Since (a few releases before) v2.6.0 there have been checks for
CONFIG_MTD_SUPERH_RESERVE. One check is still present. But a Kconfig
symbol MTD_SUPERH_RESERVE has never been added. So a few lines of dead
code can be removed.

On m86k, and maybe a few other architectures, we get this kind of
warning, due to misuse of volatile:

   drivers/mtd/maps/sc520cdp.c: In function 'sc520cdp_setup_par':
>> drivers/mtd/maps/sc520cdp.c:223:2: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [enabled by default]
   arch/m68k/include/asm/raw_io.h:22:13: note: expected 'void *' but argument is of type 'volatile long unsigned int *'

Rather than annotating the variable declaration, let's just use the
proper accessors, which add the 'volatile' qualifier to the operation.

Anyone working with an AMD Elan SC520 development or evaluation board
would be building a dedicated kernel for it, so we can make the
sc520cdp and netsc520 maps depend on MELAN. SC520_CPUFREQ already
depends on MELAN so it makes things more consistent. It also makes
kernel configuration for every other x86 user easier.

Up to now mtd-ram devices described in device trees were only accessible
if mtd-flash or mtd-rom were also configured at linux configuration
time, because MTD_PHYSMAP_OF was only available if (MTD_CFI ||
MTD_JEDECPROBE || MTD_ROM).  Allow MTD_PHYSMAP_OF selection also
when only MTD_RAM is set.

The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message.
