Hello,
Our static analysis tool finds a possible null-pointer dereference in the pcmcia driver in Linux 5.14.0-rc3:
The variable link->resource[0] is checked in: 1599: if (link->resource[0])
This indicates that link->resource[0] can be NULL. But it is dereferenced in: 1610: data->BaseAddress = link->resource[0]->start;
I am not quite sure whether this possible null-pointer dereference is real and how to fix it if it is real. Any feedback would be appreciated, thanks!
