Subject: [PATCH] mailbox: th1520: fix clock imbalance on probe failure
Date: Fri, 17 Oct 2025 07:54:14 +0200	[thread overview]
Message-ID: <20251017055414.7753-1-johan@kernel.org> (raw)

The purpose of the devm_add_action_or_reset() helper is to call the
action function in case adding an action ever fails so drop the clock
disable from the error path to avoid disabling the clocks twice.

Fixes: 5d4d263e1c6b ("mailbox: Introduce support for T-head TH1520 Mailbox driver")
Cc: Michal Wilczynski <m.wilczynski@samsung.com>
