[ Upstream commit f656b419d41aabafb6b526abc3988dfbf2e5c1ba ]
As it was before the blamed commit, s3an_nor_scan() was called after mtd size was set with params->size, and it overwrote the mtd size value with '8 * nor->page_size * nor->info->n_sectors' when XSR_PAGESIZE was set. With the introduction of s3an_post_sfdp_fixups(), we missed to update the mtd size for the s3an flashes. Fix the mtd size by updating both nor->params->size, (which will update the mtd_info size later on) and nor->mtd.size (which is used in spi_nor_set_addr_width()).
