CVE-2026-68465

In the Linux kernel, the following vulnerability has been resolved:

mmc: sdhci-esdhc-imx: fix esdhc_change_pinstate() to allow default state restore

esdhc_change_pinstate() checks for pins_100mhz and pins_200mhz at the
top of the function and returns -EINVAL if either is not defined. This
prevents the default case from ever being reached, which means devices
with a sleep pinctrl state but without high-speed pin states (100mhz/
200mhz) can never restore their default pin configuration.

Move the IS_ERR checks for pins_100mhz and pins_200mhz into their
respective switch cases.
