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
