However, between the read and the error handling path, pm_runtime_idle() is called and invokes the driver's suspend callback, which also disables the vcc regulator. This leads to an underflow of the regulator enable count if the EEPROM is not present. Move the pm_runtime_suspend() call to be after the error handling path to resolve this.
