Subject: smatch stuff: serial: ifx6x60: oops on load
Date: Mon, 20 Dec 2010 12:15:55 +0300	[thread overview]
Message-ID: <20101220091555.GR1936@bicker> (raw)

Smatch complains that the ifx6x60 driver in linux-next has a NULL
dereference.

drivers/serial/ifx6x60.c +986 ifx_spi_spi_probe(27)
	error: potential null derefence 'pl_data'.

   984          ifx_dev->spi_timer.function = ifx_spi_timeout;
   985          ifx_dev->spi_timer.data = (unsigned long)ifx_dev;
   986          ifx_dev->is_6160 = pl_data->is_6160;
                                   ^^^^^^^
"pl_data" is always NULL at this point.  Presumably this crashes on load
every time.

regards,
dan carpenter
