Subject: powerpc/kernel: Convert mmu_has_feature() to returning bool
X-Git-Tag: v4.14-rc1~2706^2~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a81dc9d9957354ee2ebc2e387cbc10cf457b9948;p=platform%2Fkernel%2Flinux-rpi.git

powerpc/kernel: Convert mmu_has_feature() to returning bool

The intention is that the result is only used as a boolean, so enforce
that by changing the return type to bool.
