Subject: ramoops: fix use of rounddown_pow_of_two()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fdb5950754eb3dedb9fea7c8828d3e51d9dbc3f7;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ramoops: fix use of rounddown_pow_of_two()

The return value of rounddown_pow_of_two wasn't evaluated, so the
operation was a no-op.
