Subject[PATCH 1/9] stringify: add HEX_STRING()
From: Randy Dunlap <rdunlap@xenotime.net>

Add HEX_STRING(value) to stringify.h so that drivers can
convert kconfig hex values (without leading "0x") to useful
hex constants.

Several drivers/media/radio/ drivers need this. I haven't
checked if any other drivers need to do this.

Alternatively, kconfig could produce hex config symbols with
leading "0x".
