Message-Id: <20110710125109.c72f9c2d.rdunlap@xenotime.net> Date: Sun, 10 Jul 2011 12:51:09 -0700 From: Randy Dunlap <rdunlap@...otime.net> To: lkml <linux-kernel@...r.kernel.org> Cc: linux-kbuild@...r.kernel.org, linux-media@...r.kernel.org, mchehab@...radead.org Subject: [PATCH 1/9] stringify: add HEX_STRING() From: Randy Dunlap <rdunlap@...otime.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".
