From f3d45ac21e464f24cb97b3f6cc68be8eef7f7b56 Mon Sep 17 00:00:00 2001 From: Xiaoming Ni Date: Sun, 14 Jul 2019 11:57:18 +0800 Subject: [PATCH] mtd: phram: Module parameters add writable permissions The phram code implements managing multiple devices through a linked list. However, due to the module parameter permission of 0, the /sys/module/phram/parameters/phram interface is missing. The command line arguments in insmod can only create one device. Therefore, add writable permissions to the module parameters, create /sys/module/phram/parameters/phram interface, and create multi-device support.
