CVE-2026-53340
i2c: imx: fix clock and pinctrl state inconsistency in runtime PM
Description
In the Linux kernel, the following vulnerability has been resolved: i2c: imx: fix clock and pinctrl state inconsistency in runtime PM In i2c_imx_runtime_suspend(), the clock is disabled before switching the pinctrl state to sleep. If pinctrl_pm_select_sleep_state() fails, the runtime suspend is aborted but the clock remains disabled, causing a system crash when the hardware is subsequently accessed. Fix this by switching the pinctrl state before disabling the clock so that a pinctrl failure leaves the clock enabled and the hardware accessible. In i2c_imx_runtime_resume(), restore the pinctrl state back to sleep if clk_enable() fails to keep the consistent.
