From fda8c908bc2d523c0770ded667dcdad29c06ff52 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 28 Sep 2022 16:57:41 +0300 Subject: docs: filesystems: sysfs: Make text and code for ->show() consistent The documentation says that ->show() should only use sysfs_emit() or sysfs_emit_at(), but example keeps outdated code. Update the code to be consistent.
