Rob Herring 897500c7ea dmaengine: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Miaoqian Lin 615a4bfc42 dmaengine: ti: Add missing put_device in ti_dra7_xbar_route_allocate
of_find_device_by_node() takes reference, we should use put_device()
to release it when not need anymore.

Miaoqian Lin c132fe78ad dmaengine: ti: Fix refcount leak in ti_dra7_xbar_route_allocate
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.

Add missing of_node_put() in to fix this.

Krzysztof Kozlowski 5d051f37f4 dmaengine: ti: drop of_match_ptr and mark of_device_id table as maybe unused
The driver can match only via the DT table so the main table should be
always used and the of_match_ptr does not have any sense (this also
allows ACPI matching via PRP0001, even though it is not relevant here).

The secondary match of_device_id tables (passed to of_match_node) should
be marked as maybe unused to fix compile testing (!CONFIG_OF on x86_64)

Wenwen Wang 2c231c0c1d dmaengine: ti: dma-crossbar: Fix a memory leak bug
In ti_dra7_xbar_probe(), 'rsv_events' is allocated through kcalloc(). Then
of_property_read_u32_array() is invoked to search for the property.
However, if this process fails, 'rsv_events' is not deallocated, leading to
a memory leak bug. To fix this issue, free 'rsv_events' before returning
the error.
