Subject: [PATCH] spi: atmel-quadspi: void return type for atmel_qspi_init()

From: Tudor Ambarus <tudor.ambarus@...rochip.com>

commit 2d30ac5ed633 ("mtd: spi-nor: atmel-quadspi: Use spi-mem interface for atmel-quadspi driver")
removed the error path from atmel_qspi_init(), but not changed the
function's return type. Set void return type for atmel_qspi_init().
