[PATCH] ASoC: brcm: fix dma_addr_t cast to pointer

From: Arnd Bergmann
Date: Wed Apr 08 2020 - 14:57:07 EST


A dma_addr_t is not a pointer and a cast causes a warning when
the sizes are different:

sound/soc/bcm/bcm63xx-pcm-whistler.c: In function 'bcm63xx_pcm_pointer':
sound/soc/bcm/bcm63xx-pcm-whistler.c:184:6: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
184 | if ((void *)prtd->dma_addr_next == NULL)

Change the comparison to NULL to an equivalent if() check that
does not warn.

Fixes: 88eb404ccc3e ("ASoC: brcm: Add DSL/PON SoC audio driver")
