Subject: ACPI: custom_method: remove meaningless null check before debugfs_remove()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7e79a69273272df016928144062b97bcb11d1122;p=linux.git

ACPI: custom_method: remove meaningless null check before debugfs_remove()

debugfs_remove() has taken null pointer into account. So it is safe
to remove the check before debugfs_remove().
