mfd: sec-core: Fix possible NULL pointer dereference when i2c_new_dummy error
commit 65aba1e04916d72b30c028730a1e31860c225412 upstream.
During probe the sec-core driver allocates dummy I2C device for RTC with
i2c_new_dummy() but return value is not checked. In case of error
(i2c_new_device(): memory allocation failure or I2C address cannot be
used) this function returns NULL which is later used by
devm_regmap_init_i2c() or i2c_unregister_device().
If i2c_new_dummy() fails for RTC device, fail also the probe for main
MFD driver.
