Some mt7603e chip has empty efuse data. In this case driver will crash due to dereferencing NULL pointer. The mt7603_eeprom_load will return success directly if the chip has no efuse data and dev->mt76.otp.data is left empty, i.e. NULL pointer. The mt7603_eeprom_init will then try to dereference dev->mt76.otp.data without checking its value. This patch adds a check around these codes to prevent kernel panic.
