The patch titled
Subject: clk: convert clock name allocations to kstrdup_const
has been removed from the -mm tree. Its filename was
clk-convert-clock-name-allocations-to-kstrdup_const.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Andrzej Hajda <a.hajda@xxxxxxxxxxx>
Subject: clk: convert clock name allocations to kstrdup_const
Clock subsystem frequently performs duplication of strings located in
read-only memory section. Replacing kstrdup by kstrdup_const allows to
avoid such operations.
