Subject: mm/madvise.c: fix return value of madvise_hwpoison()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8302423b8e85ad6caa8687f06157d43f684a42e2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mm/madvise.c: fix return value of madvise_hwpoison()

The return value outside for loop is always zero which means
madvise_hwpoison return success, however, this is not truth for
soft_offline_page w/ failure return value.
