Hello Daniel Mack,
This is a semi-automatic email about new static checker warnings.
The patch 7e8d5cd93fac: "USB: Add EHCI support for MX27 and MX31
based boards" from Oct 28, 2009, leads to the following Smatch
complaint:
drivers/usb/host/ehci-mxc.c:187 ehci_mxc_drv_remove()
error: we previously assumed 'pdata' could be null (see line 184)
drivers/usb/host/ehci-mxc.c
183
184 if (pdata && pdata->exit)
^^^^^
New check.
185 pdata->exit(pdev);
186
187 if (pdata->otg)
^^^^^^^^^^
New dereference.
188 usb_phy_shutdown(pdata->otg);
189
regards,
dan carpenter
