[PATCH] ALSA: dmaengine_pcm: No need to take runtime reference twice in pcm_pointer

[Peter Ujfalusi]

The runtime pointer has been taken in functional level so there is no need
to take it again under the if () case.

Fixes: 9d789dc047e3 ("ALSA: dmaengine_pcm: Consider DMA cache caused delay in pointer callback")

Hi Mark,

it looks like that the DMA caused delay reporting patch went in in two pieces:
fa1f875c120f ALSA: dmaengine_pcm: Consider DMA cache caused delay in pointer callback
9d789dc047e3 ALSA: dmaengine_pcm: Consider DMA cache caused delay in pointer callback

and the second one missed removing the runtime pointer initialization from the
if () case.

Regards,
Peter
