Subject: md-cluster: correct the num for comparison
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8c58f02e244d5b35fa38aa308007715d4957d4c7;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

md-cluster: correct the num for comparison


Since the node num of md-cluster is from zero, and
cinfo->slot_number represents the slot num of dlm,
no need to check for equality.
