Hello Cyril Chemparathy,
This is a semi-automatic email about new static checker warnings.
The patch 03df0f629483: "mfd: add driver for sequencer serial port"
from Jan 18, 2011, leads to the following Smatch complaint:
drivers/mfd/ti-ssp.c:407 ti_ssp_probe()
error: we previously assumed 'pdata' could be null (see line 400)
drivers/mfd/ti-ssp.c
399 sysclk = clk_get_rate(ssp->clk);
400 if (pdata && pdata->out_clock)
^^^^^
Check.
401 prediv = (sysclk / pdata->out_clock) - 1;
402 prediv = clamp(prediv, 0, 0xff);
403 ssp_rmw(ssp, REG_PREDIV, 0xff, prediv);
404
405 memset(cells, 0, sizeof(cells));
406 for (id = 0; id < 2; id++) {
407 const struct ti_ssp_dev_data *data = &pdata->dev_data[id];
^^^^^^^^^^^^^^^^^^^
Unchecked dereference.
408
409 cells[id].id = id;
regards,
dan carpenter
