[PATCH 5.4 75/85] spi: meson-spicc: fix memory leak in meson_spicc_remove

From: Greg Kroah-Hartman

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.
