6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Frank Li <Frank.Li@xxxxxxx>
commit 5b04d44d5c74e4d8aab1678496b84700b4b343fe upstream.
Fix missing call to phy_power_off() in the error path of
imx6_pcie_host_init(). Remove unnecessary check for imx6_pcie->phy
as the PHY API already handles NULL pointers.
Fixes: cbcf8722b523 ("phy: freescale: imx8m-pcie: Fix the wrong order of phy_init() and phy_power_on()")
