With ARCH=x86, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mtd/parsers/brcm_u-boot.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mtd/parsers/tplink_safeloader.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mtd/chips/cfi_util.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mtd/chips/cfi_cmdset_0020.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/mtd/maps/map_funcs.o

Add the missing invocations of the MODULE_DESCRIPTION() macro.

Corrections to these descriptions are welcomed. I'm not an expert in
this code so in most cases I've taken these descriptions directly from
code comments, Kconfig descriptions, or git logs.  History has shown
that in some cases these are originally wrong due to cut-n-paste
errors, and in other cases the drivers have evolved such that the
original information is no longer accurate.
