Wei Yongjun c29e9da56b pinctrl: nsp: Fix potential NULL dereference
platform_get_resource() may fail and return NULL, so we should
better check it's return value to avoid a NULL pointer dereference
a bit later in the code.

This is detected by Coccinelle semantic patch.

expression pdev, res, n, t, e, e1, e2;

res = platform_get_resource(pdev, t, n);
+ if (!res)
+   return -EINVAL;
... when != res == NULL
e = devm_ioremap_nocache(e1, res->start, e2);
