dmaengine: cppi41: More PM runtime fixes
Fix use of u32 instead of int for checking for negative errors values as pointed out by Dan Carpenter <dan.carpenter@oracle.com>. And while testing the PM runtime error path by randomly returning failed values in runtime resume, I noticed two more places that need fixing: - If pm_runtime_get_sync() fails in probe, we still need to do pm_runtime_put_sync() to keep the use count happy. We could call pm_runtime_put_noidle() on the error path, but we're just going to call pm_runtime_disable() after that so pm_runtime_put_sync() will do what we want - We should print an error if pm_runtime_get_sync() fails in cppi41_dma_alloc_chan_resources() so we know where it happens Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Fixes: 740b4be3 ("dmaengine: cpp41: Fix handling of error path") Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
