Subject: zd1201: do not use stack as URB transfer_buffer
From: Jussi Kivilinna <jussi.kivilinna@xxxxxx>
commit 1206ff4ff9d2ef7468a355328bc58ac6ebf5be44 upstream.
Patch fixes zd1201 not to use stack as URB transfer_buffer. URB buffers need
to be DMA-able, which stack is not.
Patch is only compile tested.
