Problem: rmmod meson_gx_mmc - not stable without spi_master_suspend call and we can get stuck when try unload this module
rmmod meson_gx_mmc ... [ 421.108614] Deleting MTD partitions on "spi0.0": [ 424.219862] spi_master spi0: Failed to power device: -13 ... lsmod | grep spi spi_meson_spifc 16384 -1
Solution: just add spi_master_suspend(master) call
