Subject: clk: xgene: Delete duplicated name field
X-Git-Tag: firefly_0821_release~176^2~908^2~125
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=78e50c6def9cca448dbb028b57ec92a1589edc07;p=firefly-linux-kernel-4.4.55.git

clk: xgene: Delete duplicated name field

X-Gene clocks implement it's name in the clock private struct.
This is a duplication of the name field. We can delete the field
and rely on the common implementation to retrieve the name.
