-Subject: [PATCH 388/703] bcm2835-mmc: Fix DMA channel leak
-
-The BCM2835 MMC host driver requests a DMA channel on probe but neglects
-to release the channel in the probe error path and on driver unbind.
-
-I'm seeing this happen on every boot of the Compute Module 3: On first
-driver probe, DMA channel 2 is allocated and then leaked with a "could
-not get clk, deferring probe" message. On second driver probe, channel 4
-is allocated.
-
-Fix it.
