From e567ec849a9aba4cd683ea23bd57c878b59714c4 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 19 Jul 2020 10:15:32 -0600 Subject: [PATCH] mtd: spi-nor: Tidy up error handling / debug code The -ENODEV error value in spi_nor_read_id() is incorrect since there clearly is a device - it just cannot be supported. Use -ENOMEDIUM instead which has the virtue of being less common. Fix the return value in spi_nor_scan(). Also there are a few printf() statements which should be debug() since they bloat the code with unused strings at present. Fix those while here.
