Subject: dw_dmac: remove redundant check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=21e93c1e7dae0e8b1914a522c331f0f7763fa89d;p=linux-beck.git

dw_dmac: remove redundant check

There is no need to check the callback_required parameter, due to we check the
callback pointer to be a non-NULL.
