Merge mt76x0_dev data structure in mt76x02_dev one and remove duplicated code. Remove unused definition in mt76x0.h. Moreover merge mt76x0_caldata and mt76x02_rx_freq_cal data structures. This is a preliminary patch for rxwi unification. Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
