From: Robert Jarzmik
Date: Tue Aug 18 2015 - 02:19:52 EST


This fixes the following error:
drivers/dma/pxa_dma.c: In function âdbg_show_requester_chanâ:
drivers/dma/pxa_dma.c:192:2: error: void value not ignored as it ought to be
pos += seq_printf(s, "DMA channel %d requester :\n", phy->idx);
^
drivers/dma/pxa_dma.c:197:8: error: void value not ignored as it ought to be
!!(drcmr & DRCMR_MAPVLD));
^
scripts/Makefile.build:258: recipe for target 'drivers/dma/pxa_dma.o' failed
