Hello Kay Sievers,
This is a semi-automatic email about new static checker warnings.
The patch ca22e56debc5: "driver-core: implement 'sysdev'
functionality for regular devices and buses" from Dec 14, 2011, leads
to the following Smatch complaint:
drivers/base/bus.c +1200 subsys_interface_unregister()
warn: variable dereferenced before check 'sif' (see line 1196)
drivers/base/bus.c
1195 {
1196 struct bus_type *subsys = sif->subsys;
^^^^^^^^^^^
New dereference.
1197 struct subsys_dev_iter iter;
1198 struct device *dev;
1199
1200 if (!sif)
^^^^
New check.
1201 return;
1202
regards,
dan carpenter
