When in the PREPARE state of a switchdev transaction, check if the
requested VLAN is not already configured on the switch port. This keeps
us from getting into a WARNING as below.

MFD_CORE is selected by MFD_HI6421_SPMI, and MFD_CORE depends on
HAS_IOMEM. If HAS_IOMEM is not set, this can cause a conflict in Kconfig
resolution, yielding the following error:
WARNING: unmet direct dependencies detected for MFD_CORE
Depends on [n]: HAS_IOMEM [=n]
Selected by [y]:
- MFD_HI6421_SPMI [=y] && STAGING [=y] && OF [=y] && SPMI [=y]
By specifying HAS_IOMEM as a dependency for MFD_HI6421_SPMI (as
SPMI_HISI3670 already dows), this issue is resolved, and no such warning
appears when building on architectures without HAS_IOMEM.

drivers/staging/hikey9xx/hisi-spmi-controller.c:239:25: warning: cast from restricted __be32
Rationale for #164:
data is declared as u32, and it is read and then converted by means of
be32_to_cpu(). Said function expects a __be32 but data is u32, therefore
there's a type missmatch here.
Rationale for #239:
Is the dual of #164. This time data going to be written so it
needs to be converted from cpu to __be32, but writel() expects u32 and the
output of cpu_to_be32 returns a __be32.

gasket_interrupt_set_eventfd() misses to call eventfd_ctx_put() in an

There is the same issue in gasket_interrupt_clear_eventfd(), Add the
missed function call to fix it.

When DMA_RALINK is enabled and DMADEVICES is disabled, it results in the
following Kbuild warnings:
WARNING: unmet direct dependencies detected for DMA_ENGINE
Depends on [n]: DMADEVICES [=n]
Selected by [y]:
- DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n]
WARNING: unmet direct dependencies detected for DMA_VIRTUAL_CHANNELS
Depends on [n]: DMADEVICES [=n]
Selected by [y]:
- DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n]
The reason is that DMA_RALINK selects DMA_ENGINE and DMA_VIRTUAL_CHANNELS
without depending on or selecting DMADEVICES while DMA_ENGINE and
DMA_VIRTUAL_CHANNELS are subordinate to DMADEVICES. This can also fail
building the kernel as demonstrated in a bug report.
Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.

mt7621-pci 1e140000.pcie: Error requesting resources
mt7621-pci: probe of 1e140000.pcie failed with error -16
...
With commit 669cbc7081 ("PCI: Move DT resource setup into
devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated
into resources when the host bridge is allocated. The resources are
requested as well, but that happens a 2nd time for this driver in
mt7621_pcie_request_resources(). Hence we should avoid this second
request.
Also, the bus ranges was also populated by default, so we can remove
it from mt7621_pcie_request_resources() to avoid the following trace
if we don't avoid it:
pci_bus 0000:00: busn_res: can not insert [bus 00-ff]
under domain [bus 00-ff] (conflicts with (null) [bus 00-ff])
Function 'mt7621_pcie_request_resources' has been renamed into
'mt7621_pcie_add_resources' which now is a more accurate name
for this function.
