[PATCH 2/4] arm: plat-s3c24xx: dma: drop return codes in void function

[w.sang@pengutronix.de (Wolfram Sang)]

Commit bb072c3c (ARM / Samsung: Use struct syscore_ops for "core" power
management) turned s3c2410_dma_resume_chan() from int to void. So, drop
the actual return values, too. Fixes:

arch/arm/plat-s3c24xx/dma.c: In function 's3c2410_dma_resume_chan':
arch/arm/plat-s3c24xx/dma.c:1238:3: warning: 'return' with a value, in function returning void
arch/arm/plat-s3c24xx/dma.c:1250:2: warning: 'return' with a value, in function returning void
