Subject: powerpc/mm: Parenthesise IS_ENABLED() in if condition
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fbef66f0adcddf4475e19f3d09df22fb34e633f6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc/mm: Parenthesise IS_ENABLED() in if condition

Currently IS_ENABLED() produces an expression surrounded by parentheses,
which allows this code to compile, generating eg:

    else if (1 || 0)
        hpte_init_native();

However a change to the macro in the kbuild tree will break this in
future by removing the parentheses.
