Wysocki" <rafael.j.wysocki@...el.com>, "Kumar P, Mahesh" <mahesh.kumar.p@...el.com>, linux-kernel@...r.kernel.org, linux-acpi@...r.kernel.org Cc: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> Subject: [PATCH v5 2/5] x86: pmc_atom: don't check for NULL twice debugfs_remove_recursive() is NULL-aware, thus, we may safely remove the check here. There is no need to assing NULL to variable since it will be not used anywhere.
