[PATCH v1 1/1] docs: filesystems: sysfs: Make text and code for ->show() consistent

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

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sysfs_emit_at(), but example keeps outdated code.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.

Fixes: 2efc459d06f1 ("sysfs: Add sysfs_emit and sysfs_emit_at to format sysfs output")
