Subject: clk: mvebu: armada-37xx-periph: Fix wrong return value in get_parent
Git-commit: 616bf80d381da13fbb392ebff06f46f946e3ee84
Patch-mainline: v4.19-rc1
References: fate#326470
The return value of the get_parent operation is a u8, whereas a -EINVAL
was returned. This wrong value was return if the value was bigger that
the number of parent but this case was already handled by the core.
So we can just remove this chunk of code to fix the issue.
