- Summary
- i2c: imx: fix clock and pinctrl state inconsistency in runtime PM
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
i2c: imx: fix clock and pinctrl state inconsistency in runtime PM
In i2cimxruntimesuspend(), the clock is disabled before switching the pinctrl state to sleep. If pinctrlpmselectsleep_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 i2cimxruntimeresume(), restore the pinctrl state back to sleep if clkenable() fails to keep the consistent.
