Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
dmaengine: qcom: bam_dma: fix runtime PM underflow<br />
<br />
Commit dbad41e7bb5f ("dmaengine: qcom: bam_dma: check if the runtime pm enabled")<br />
caused unbalanced pm_runtime_get/put() calls when the bam is<br />
controlled remotely. This commit reverts it and just enables pm_runtime<br />
in all cases, the clk_* functions already just nop when the clock is NULL.<br />
<br />
Also clean up a bit by removing unnecessary bamclk null checks.
