drivers/rtc/rtc-max8998.c: check for pdata presence before dereferencing
Currently the driver can crash with a NULL pointer dereference if no pdata is provided, despite of successful registration of the MFD part. This patch fixes the problem by adding a NULL check before dereferencing the pdata pointer.
