Subject: [PATCH 0/4] dmaengine: Remove unneeded ERROR checks before clk_xxx
This patch set tries to remove unneeded ERROR check before clk_xxx.
clk_put() already uses !clk and IS_ERR(clk) to check ERROR or NULL.
clk_disable_unprepare() already checks ERROR by using IS_ERR_OR_NULL.
Remove unneeded ERROR or NULL check before them.
