From b341f7882f04cc70b7437583f012a8d93fbfb00e Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 20 Oct 2012 01:06:24 +0200 Subject: kconfig: add a function to get the CONFIG_ prefix Currently, we get the CONFIG_ prefix via the CONFIG_ macro, which means the CONFIG_ prefix is hard-coded at compile time. This goes against having a run-time defined CONFIG_ prefix. Add a function that returns the CONFIG_ prefix to use (but keep the current hard-coded behavior, to be changed in a later patch). To avoid touching all the code that uses the CONFIG_ macro, we just undef it, and define it to be a call to the function. Signed-off-by: "Yann E.
