Subject: [PATCH] spi: amd: Drop superfluous member from struct amd_spi
References: jsc#SLE-15356
Git-commit: 36c72a58d472b4032e09f165ea064a0251c9df07
Patch-mainline: v5.8-rc1
The AMD SPI driver stores a pointer to the spi_master in struct amd_spi
so that it can get from the latter to the former in amd_spi_fifo_xfer().
It's simpler to just pass the pointer from the sole caller
amd_spi_master_transfer() and drop the pointer from struct amd_spi.
