Subject: dmaengine: sh: shdmac: don't open code of_device_get_match_data()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6fb5629987239c6a8438fab8fd324b7724e49453;p=linux-beck.git

dmaengine: sh: shdmac: don't open code of_device_get_match_data()

This change will also make Coverity happy by avoiding a theoretical NULL
pointer dereference; yet another reason is to use the above helper function
to tighten the code and make it more readable.
