Arnd Bergmann 10b3e22317 dmaengine: k3: fix duplicate function definition
Commit db08425ebd ("dmaengine: k3: Split device_control") introduced
two new helper functions, which unfortunately have the same names
as the existing suspend/resume functions, resulting in a build error
when CONFIG_PM_SLEEP is enabled:

drivers/dma/k3dma.c:823:12: error: conflicting types for 'k3_dma_resume'
 static int k3_dma_resume(struct device *dev)
            ^
drivers/dma/k3dma.c:625:12: note: previous definition of 'k3_dma_resume' was here
 static int k3_dma_resume(struct dma_chan *chan)

While splitting device control in db08425ebd ("dmaengine: k3:
Split device_control") new function with the same 'k3_dma_resume' name
was added, leading to build error:

Maxime Ripard db08425ebd dmaengine: k3: Split device_control
Split the device_control callback of the Hisilicon K3 DMA driver to make use
of the newly introduced callbacks, that will eventually be used to retrieve
slave capabilities.

Jingoo Han af2d3139e1 dmaengine: k3dma: Add CONFIG_PM_SLEEP to suspend/resume functions
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

Kiran Padwal cd166280b7 dmaengine: Remove .owner field for driver
There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

Maxime Ripard 25741ff296 dmaengine: k3: Remove chancnt affectations
chanctnt is already filled by dma_async_device_register, which uses the channel
list to know how much channels there is.

Since it's already filled, we can safely remove it from the drivers' probe
function.
