Subject[PATCH 5.5 228/257] clk: ingenic/TCU: Fix round_rate returning error
Date
From: Paul Cercueil <paul@crapouillou.net>

commit edcc42945dee85e9dec3737f3dbf59d917ae5418 upstream.

When requesting a rate superior to the parent's rate, it would return
-EINVAL instead of simply returning the parent's rate like it should.

Fixes: 4f89e4b8f121 ("clk: ingenic: Add driver for the TCU clocks")
