And that way you could also print the error code. You could also use dev_err("bla (%pe)\n", ERR_PTR(ret)); -michael

Add an error message when failing to exit the 4-byte address mode. Do not stop the execution and go through the spi_nor_soft_reset() method if used, in the hope that the flash will default to 3-byte address mode after the reset.
