[PATCH 5/5] kconfig: nconf: refactor attributes setup code
From: Masahiro Yamada
Date: Sat Apr 10 2021 - 15:46:24 EST
The current attributes setup code is strange; the array attribute[]
is set to values outside the range of the attribute_t enum.
At least,
attributes_t attributes[ATTR_MAX+1] = {0};
... should be
int attribute[ATTR_MAX+1] = {0};
Also, there is no need to hard-code the color-pair numbers in
attributes_t.
The current code is horribly screwed up. Rewrite it.
