From eb726c322020b95bfc1fbf0e83d0fd41c2500e96 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Tue, 7 Dec 2021 16:02:42 +0200 Subject: [PATCH] mtd: spi-nor: core: Don't use mtd_info in the NOR's probe sequence of calls 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. It's safe to drop xilinx's setting of nor->mtd.size, now that we use nor->params->size in spi_nor_set_addr_width().
