Chen-Tsung Hsieh 0e1cd4edef mtd: spi-nor: core: Check written SR value in spi_nor_write_16bit_sr_and_check() ... [ Upstream commit 70dd83d737d8900b2d98db6dc6b928c596334d37 ] Read back Status Register 1 to ensure that the written byte match the received value and return -EIO if read back test failed. Without this patch, spi_nor_write_16bit_sr_and_check() only check the second half of the 16bit. It causes errors like spi_nor_sr_unlock() return success incorrectly when spi_nor_write_16bit_sr_and_check() doesn't write SR successfully.
