[PATCH u-boot-spi v3 04/10] mtd: spi-nor-core: Check return value of write_disable() in spi_nor_erase()

["Marek Behún" <kabel@kernel.org>]

From: Marek Behún <marek.behun@nic.cz>

The cleanup code of spi_nor_erase() function calls write_disable(), but
does not return it's return value even in case of failure. Fix this.
