From 5f340402bbfc1ee75e7b62b98f6ad85e14ce587c Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Fri, 17 Dec 2021 14:26:35 +0200 Subject: [PATCH] mtd: spi-nor: Remove debugfs entries that duplicate sysfs entries SPI NOR sysfs defines partname and jedec_id device attributes, which duplicate the information from debugfs. Since the sysfs directory structure and the attributes in each directory define an ABI between the kernel and user space, thus it can never be removed, remove the debugfs entries so that we don't duplicate the information.
