Subject: usb: misc: brcmstb-usb-pinmap: check return value after calling platform_get_resource()
From: Yang Yingliang <yangyingliang@xxxxxxxxxx>
commit fbf649cd6d64d40c03c5397ecd6b1ae922ba7afc upstream.
It will cause null-ptr-deref if platform_get_resource() returns NULL,
we need check the return value.
