ARM: cleanup: debugfs error handling Debugfs functions return NULL when they fail, or an error pointer when not configured. The intention behind the error pointer is that it appears as a valid pointer to the caller, and so the caller continues inspite of debugfs not being available. Debugfs failure should only ever be checked with (!ptr) and not the IS_ERR*() functions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
