stable inclusion from linux-4.19.203 commit 683b47d0ebb10ba0d272604b09686e023d10d40c
--------------------------------
commit 8311ee2164c5cd1b63a601ea366f540eae89f10e upstream.
In meson_spicc_probe, the error handling code needs to clean up master by calling spi_master_put, but the remove function does not have this function call. This will lead to memory leak of spicc->master.
