[BUG] scsi: pcmcia: nsp_cs: possible null-pointer dereference in nsp_cs_config()

[Li Tuo]

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!
