ftrace: Clear bits properly in reset_iter_read()
commit 70f77b3f7ec010ff9624c1f2e39a81babc9e2429 upstream. There is a typo here where '&' is used instead of '|' and it turns the statement into a noop. The original code is equivalent to: iter->flags &= ~((1 << 2) & (1 << 4)); Link: http://lkml.kernel.org/r/20120609161027.GD6488@elgon.mountain Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
