CVE-2026-45874: phy: freescale: imx8qm-hsio: fix NULL pointer dereference
In the Linux kernel, the following vulnerability has been resolved:
phy: freescale: imx8qm-hsio: fix NULL pointer dereference
During the probe the refclkpad pointer is set to NULL if the 'fsl,refclk-pad-mode' property is not defined in the devicetree node. But in imxhsioconfigureclkpad() this pointer is unconditionally used which could result in a NULL pointer dereference. So check the pointer before to use it.
