Subject: [PATCH] ALSA: dmaengine_pcm: No need to take runtime reference twice in pcm_pointer
Git-commit: f9c23615c688270d2a383bd752f7a54a7137d596
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
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")
