Subject: [PATCH] Bluetooth: btmtksdio: Fix spurious ownership error logs
Date: Mon, 14 Sep 2026 09:46:31 +0000 [thread overview]
Message-ID: <20260914094631.3222026-1-tzungbi@kernel.org> (raw)
In btmtksdio_fw_pmctrl(), if an early operation fails (like clearing
the mailbox ACK), it jumps to the `out:` label and spuriously prints
"Cannot return ownership to device".
Evaluate the ownership return errors locally to ensure the error log is
only printed if the actual ownership transaction fails.
