Subject: dw_dmac: print correct number of scanned descriptors
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2ab3727634bf88583b40541ea32df6dadfb8cc6c;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

dw_dmac: print correct number of scanned descriptors

In case the first descriptor we found is available, the counter still remains 0
value which is wrong. This patch fixes the counter behaviour.
