[PATCH v2] spi: spi-at91-usart: Fix wrong goto jump label when spi_alloc_master() returns error.

From: zpershuai
Date: Tue Jun 08 2021 - 22:49:48 EST


When spi_alloc_master() returns null pointer, it’s no need to use
spi_master_put() to release the memory, although spi_master_put()
function has null pointer checks.
