From: Yaowei Bai Date: Tue, 17 Nov 2015 07:25:24 +0000 (+0800) Subject: security/capability.h: cap_issubset/isclear can be boolean X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e42852bf88144affc227884b62637118ba74b783;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git security/capability.h: cap_issubset/isclear can be boolean This patch makes cap_issubset/isclear return bool due to these functions only using either one or zero as their return value. No functional change.
