Tomasz Figa 43c523bff7 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.
