Subject: [PATCH 5.8 024/148] opp: Put opp table in dev_pm_opp_set_rate() if _set_opp_bw() fails

From: Stephen Boyd <swboyd@...omium.org>

commit d4ec88d205583ac4f9482cf3e89128589bd881d2 upstream.

We get the opp_table pointer at the top of the function and so we should
put the pointer at the end of the function like all other exit paths
from this function do.

Cc: v5.8+ <stable@...r.kernel.org> # v5.8+
Fixes: b00e667a6d8b ("opp: Remove bandwidth votes when target_freq is zero")
