mtd: mxc-nand: no need to check for validity of platform driver data
The probe function calls platform_set_drvdata with a valid pointer when the probe is successful. As mxcnd_suspend and mxcnd_resume are only called on bound devices, platform_get_drvdata always returns non-NULL. This fix isn't critical as the pointer is always valid so it doesn't matter if the compiler generated code for it or not.
