[PATCH v2] ASoC: amd: move the call to devm_kzalloc below platform_get_resource()

[PATCH v2] ASoC: amd: move the call to devm_kzalloc below platform_get_resource()

[Defang Bo]

Just as the commit <4cb79ef9c6c4>("ASoC: amd: Fix potential NULL pointer dereference"),it makes no sense to allocate any resources if platform_get_resource fails,so move the call to devm_kzalloc() below the mentioned code.

As I said on my previous mail:

| Please keep your commit message wrapped at below 80 columns.

Please don't ignore review comments, people are generally making them
for a reason and are likely to have the same concerns if issues remain
unaddressed.  Having to repeat the same comments can get repetitive and
make people question the value of time spent reviewing.  If you disagree
with the review comments that's fine but you need to reply and discuss
your concerns so that the reviewer can understand your decisions.

This appears to add new whitespace, it doesn't seem to do what the
commit log says?
