In mtd_ioctl MEMGETREGIONINFO the region_user_info pointer ur
is cast in __kernel space. This produces a number of sparse warnings
like:

warning: cast removes address space of expression
warning: incorrect type in initializer (different address spaces)
   expected unsigned int const [noderef] <asn:1>*register __p
   got unsigned int *<noident>

Since argp is already a void __user * just use it dirrectly without
the cast and make ur a __user *.

In the inline function cfi_build_cmd_addr, the cast of cmd_ofs to an
uint8_t produces a sparse warning of the type:

warning: cast truncates bits from constant value (2aa becomes aa)

Quiet the warning by masking cmd_ofs with 0xff and remove the cast.

The clock must already be off after mtd->suspend.  Disabling it again
results in an negative overflow of the clock usage count.  This didn't
hurt as mxcnd_resume undid it after wake up.

The probe function calls platform_set_drvdata with a valid pointer when
the probe is successful.  As mxcnd_suspend and mxcnd_resume are only
called on bound devices, platform_get_drvdata always returns non-NULL.

This fix isn't critical as the pointer is always valid so it doesn't
matter if the compiler generated code for it or not.

crash_kexec gets called before kmsg_dump(KMSG_DUMP_OOPS) if
panic_on_oops is set, so the kernel log buffer is not stored
for this case.

This patch adds a KMSG_DUMP_KEXEC dump type which gets called
when crash_kexec() is invoked. To avoid getting double dumps,
the old KMSG_DUMP_PANIC is moved below crash_kexec(). The
mtdoops driver is modified to handle KMSG_DUMP_KEXEC in the
same way as a panic.
