support/kconfig/merge_config.sh: fix merging buildroot config files
This patch allows us to define config prefix with CONFIG_ environment variable. By setting the proper config prefix, we will have proper 'redundant configuration warnings' when we use '-r -m' options. This is actually already in mainline for v4.20-rc1: 2cd3faf87d2d8f6123adf34741b9a7b98828a76f ("merge_config.sh: Allow to define config prefix") Signed-off-by: Nasser Afshin <afshin.nasser@gmail.com> Reviewed-by: Petr Vorel <petr.vorel@gmail.com> Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
