mfd: mc13xxx: Fix a missing check of a register-read failure When mc13xxx_reg_read() fails, "old_adc0" is uninitialized and will contain random value. Further execution uses "old_adc0" even when mc13xxx_reg_read() fails. The fix checks the return value of mc13xxx_reg_read(), and exits the execution when it fails.
