Subject: [PATCH v4 01/13] mtd: spi-nor: core: Don't use mtd_info in the NOR's probe sequence of calls
Date: Mon, 22 Nov 2021 11:50:08 +0200	[thread overview]
Message-ID: <20211122095020.393346-2-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20211122095020.393346-1-tudor.ambarus@microchip.com>

Use NOR parameters in the probe's sequence of calls, thus
nor->params->size instead of nor->mtd.size and let the mtd_info
fields be used by the mtd calls (mtd->_erase, mtd->_read, mtd->_write).
mtd_info fields should not be used during probe because we haven't
registered mtd yet.
