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.

Wan Jiabing (4):
  dmaengine: ep93xx_dma: Remove unneeded ERROR check before clk_put
  dmaengine: sprd-dma: Remove unneeded ERROR check before clk_disable_unprepare
  dmaengine: ste_dma40: Remove unneeded ERROR and NULL check in ste_dma40
  dmaengine: xgene-dma: Remove unneeded ERROR check before clk_disable_unprepare
