Wei Yongjun 492b804d7f gpio: pxa: Fix potential NULL dereference
[ Upstream commit 9506755633 ]

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.

... when != res == NULL
e = devm_ioremap(e1, res->start, e2);
