When a remove platform device callback returns an error code, the driver
core emits an error message ("remove callback returned a non-zero value.
This will be ignored.\n") and still removes the device. As the driver
already emits a more specific error message, return 0 to suppress the
core's error message.
This is a preparation for making platform remove callbacks return void.

[drivers/rtc/rtc-mpfs.c:219]: (style) Variable 'pending' is assigned a value that is never used.
The fetched CONTROL_REG stored in pending is unused and partially
duplicates the functionality of the later call to mpfs_rtc_clear(). This looks
like leftover development code, so remove pending.

Taking a lock at the beginning of .remove() doesn't prevent new readers.
With the existing approach it can happen, that a read occurs just when
the lock was taken blocking the reader until the lock is released at the
end of the remove callback which then accessed *data that is already
freed then.
To actually fix this problem the hwmon core needs some adaption. Until
this is implemented take the optimistic approach of assuming that all
readers are gone after hwmon_device_unregister() and
sysfs_remove_group() as most other drivers do. (And once the core
implements that, taking the lock would deadlock.)
So drop the lock, move the reset to after device unregistration to keep
the device in a workable state until it's deregistered. Also add a error
message in case the reset fails and return 0 anyhow. (Returning an error
code, doesn't stop the platform device unregistration and only results
in a little helpful error message before the devm cleanup handlers are
called.)

Some on-chip peripheral modules(for eg:- rspi) on RZ/G2L SoC
use the same signal for both interrupt and DMA transfer requests.
The signal works as a DMA transfer request signal by setting
DMARS, and subsequent interrupt requests to the interrupt controller
are masked.
We can re-enable the interrupt by clearing the DMARS.
This patch adds device_synchronize callback for clearing
DMARS and thereby allowing DMA consumers to switch to
interrupt mode.

It's not allowed to quit remove early without cleaning up completely.
Otherwise this results in resource leaks that probably yield graver
problems later. Here for example some tasklets might survive the lifetime
of the sprd-dma device and access sdev which is freed after .remove()
returns.
As none of the device freeing requires an active device, just ignore the
return value of pm_runtime_get_sync().

In certain cases where the DMA client bus gets corrupted or if the
end device ceases to send/receive data, DMA can wait indefinitely
for the data to be received/sent. Attempting to terminate the transfer
will put the DMA in pause flush mode and it remains there.
The channel is irrecoverable once this pause times out in Tegra194 and
earlier chips. Whereas, from Tegra234, it can be recovered by disabling
the channel and reprograming it.
Hence add a new terminate() function that ignores the outcome of
dma_pause() so that terminate_all() can proceed to disable the channel.

if a given ib_device can be used in P2PDMA transfers. This ensures
the ib_device is not using virt_dma and also that the underlying
dma_device supports P2PDMA.

The dma_map operations now support P2PDMA pages directly. So remove
the calls to pci_p2pdma_[un]map_sg_attrs() and replace them with calls
to dma_map_sgtable().
dma_map_sgtable() returns more complete error codes than dma_map_sg()

Call pci_p2pdma_map_segment() when a PCI P2PDMA page is seen so the bus
address is set in the dma address and the segment is marked with
sg_dma_mark_bus_address(). iommu_map_sg() will then skip these segments.
Then, in __finalise_sg(), copy the dma address from the input segment
to the output segment. __invalidate_sg() must also learn to skip these
segments.
A P2PDMA page may have three possible outcomes when being mapped:
1) If the data path between the two devices doesn't go through
the root port, then it should be mapped with a PCI bus address
2) If the data path goes through the host bridge, it should be mapped
normally with an IOMMU IOVA.
3) It is not possible for the two devices to communicate and thus
the mapping operation should fail (and it will return -EREMOTEIO).
Similar to dma-direct, the sg_dma_mark_pci_p2pdma() flag is used to
indicate bus address segments. On unmap, P2PDMA segments are skipped
over when determining the start and end IOVA addresses.
With this change, the flags variable in the dma_map_ops is set to
DMA_F_PCI_P2PDMA_SUPPORTED to indicate support for P2PDMA pages.

Add pci_p2pdma_map_segment() as a helper for dma_map_sg()
implementations. It takes an scatterlist segment that must point to a
pci_p2pdma struct page and will map it if the mapping requires a bus
address.
The return value indicates whether the mapping required a bus address
or whether the caller still needs to map the segment normally. If the
segment should not be mapped, -EREMOTEIO is returned.
This helper uses a state structure to track the changes to the
pgmap across calls and avoid needing to lookup into the xarray for
every page.
The prototype for the helper is added to dma-map-ops.h as it is only
useful to dma map implementations and don't need to pollute the public
pci-p2pdma header.

Attempt to find the mapping type for P2PDMA pages on the first
DMA map attempt if it has not been done ahead of time.
Previously, the mapping type was expected to be calculated ahead of
time, but if pages are to come from userspace then there's no
way to ensure the path was checked ahead of time.
This change will calculate the mapping type if it hasn't pre-calculated
so it is no longer invalid to call pci_p2pdma_map_sg() before the mapping
type is calculated, so drop the WARN_ON when that is the case.

Introduce a dma_flags field in struct scatterlist. These flags will be
used by dma_[un]map_sg_p2pdma() to determine when a given SGL segments
dma_address points to a PCI bus address. dma_unmap_sg_p2pdma() will need
to perform different cleanup when a segment is marked as a bus address.
The dma_flags field will fit in the existing padding on 64BIT systems
(assuming CONFIG_NEED_SG_DMA_LENGTH is also set).
The new bit will only be used when CONFIG_PCI_P2PDMA is set; this means
PCI P2PDMA will require CONFIG_64BIT. This should be acceptable as the
majority of P2PDMA use cases are restricted to newer root complexes and
roughly require the extra address space for memory BARs used in the
transactions.

The second operand of a '&&' operator has no impact on expression
result for cases 400 and 512 in SiS_GetModeID().
Judging by the logic and the names of the variables, in both cases a
typo was made.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

devm_ioremap_resource
This has several advantages:
- No need for manual undo of the two functions in the error path and
the remove function.
- Drops error handling in .remove()
Note that returning early in .remove() yields resource leaks that
often result in access of freed memory or unmapped registers later.
- Fixes a resource leak
request_mem_region allocates memory for the returned pointer that was
never freed.

No source file but the driver itself includes the header containing the
platform data definition. The last user is gone since commit
8485adf17a15 ("ARM: imx: Remove imx device directory").
Move the remaining symbols directly into the driver and remove the then
unused header file.

8485adf17a15 ("ARM: imx: Remove imx device directory").
So we can safely drop platform data support.

In clcdfb_of_init_display(), we should call of_node_put() for the
references returned by of_graph_get_next_endpoint() and
of_graph_get_remote_port_parent() which have increased the refcount.
Besides, we should call of_node_put() both in fail path or when
the references are not used anymore.
