Lu Huang 52f6a065e0 wifi: mt76: mt7996: fix uninitialized buf read in mt7996_variant_fem_init() ... When the eFuse block covering MT7976C_EFUSE_OFFSET is invalid, mt7996_mcu_get_eeprom() returns -EINVAL without writing buf, but mt7996_variant_fem_init() tolerates -EINVAL and keeps running, so buf[idx] == 0xc reads uninitialized stack memory. A stale 0x0c byte misclassifies a 0x7976 aDie as 7976C, selects MT7996_FEM_INT and the wrong default EEPROM, overriding valid calibration data. Only consult the eFuse byte when the read succeeded; with an invalid eFuse, fall back to the three explicit aDie version checks.
