Subject: [PATCH] PCI: dw-rockchip: Fix function call sequence in rockchip_pcie_phy_deinit
Date: Thu, 17 Apr 2025 16:21:18 +0200	[thread overview]
Message-ID: <20250417142138.1377451-1-didi.debian@cknow.org> (raw)

The documentation for the phy_power_off() function explicitly says

  Must be called before phy_exit().

So let's follow that instruction.

Fixes: 0e898eb8df4e ("PCI: rockchip-dwc: Add Rockchip RK356X host controller driver")
Cc: stable@vger.kernel.org	# v5.15+
