Subject: [PATCH] Bluetooth: btintel_pcie: Fix the error handling path of btintel_pcie_probe()
Date: Mon, 20 May 2024 09:41:57 +0200
Message-ID: <692b4749f4267436363a5a8840140da8cd8858a1.1716190895.git.christophe.jaillet@wanadoo.fr>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Some resources freed in the remove function are not handled by the error
handling path of the probe.

Add the needed function calls.

Fixes: c2b636b3f788 ("Bluetooth: btintel_pcie: Add support for PCIe transport")

Compile tested only.
Maybe incomplete.
