Subject: dmaengine: coh901318: use NULL for pointer initialization
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d943df870572e4774abfb16ef20c9ec28edbd94c;p=linux-beck.git

dmaengine: coh901318: use NULL for pointer initialization

Sparse complains:
drivers/dma/coh901318_lli.c:78:31: warning: Using plain integer as NULL pointer
drivers/dma/coh901318_lli.c:91:39: warning: Using plain integer as NULL pointer

Use NULL for pointer initialization rather than plain integer
