ASoC: sirf: Fix potential NULL pointer dereference
commit ae1c696a480c67c45fb23b35162183f72c6be0e1 upstream.
There is a potential execution path in which function
platform_get_resource() returns NULL. If this happens,
we will end up having a NULL pointer dereference.
Fix this by replacing devm_ioremap with devm_ioremap_resource,
which has the NULL check and the memory region request.
This code was detected with the help of Coccinelle.
