2021-04-12dmaengine: tegra20: Fix runtime PM imbalance on errorDinghao Liu
pm_runtime_get_sync() will increase the runtime PM counter even it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error.

2021-04-12dmaengine: Fix a double free in dma_async_device_registerLv Yunlong
In the first list_for_each_entry() macro of dma_async_device_register, it gets the chan from list and calls __dma_async_device_channel_register (..,chan). We can see that chan->local is allocated by alloc_percpu() and it is freed chan->local by free_percpu(chan->local) when __dma_async_device_channel_register() failed. But after __dma_async_device_channel_register() failed, the caller will goto err_out and freed the chan->local in the second time by free_percpu(). The cause of this problem is forget to set chan->local to NULL when chan->local was freed in __dma_async_device_channel_register(). My patch sets chan->local to NULL when the callee failed to avoid double free.

Introduce a heler io_free_file_tables() doing all the cleaning, there are several places where it's hand coded. Also move all allocations into io_sqe_alloc_file_tables() and rename it, so all of it is in one place.

2021-04-11io_uring: don't quiesce intial files registerPavel Begunkov
There is no reason why we would want to fully quiesce ring on IORING_REGISTER_FILES, if it's already registered we fail.

2021-04-11io_uring: set proper FFS* flags on reg file updatePavel Begunkov
Set FFS_* flags (e.g. FFS_ASYNC_READ) not only in initial registration but also on registered files update. Not a bug, but may miss getting profit out of the feature.

2021-04-11io_uring: put link timeout req consistentlyPavel Begunkov
Don't put linked timeout req in io_async_find_and_cancel() but do it in io_link_timeout_fn(), so we have only one point for that and won't have to do it differently as it's now (put vs put_deferred). Btw, improve a bit io_async_find_and_cancel()'s locking.
