Subject: powerpc/kernel: Convert cpu_has_feature() to returning bool
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6574ba950bbe9ab2460f8143018d93d15cacf5be;p=linux-beck.git

powerpc/kernel: Convert cpu_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.
