b156117aed phy: rockchip-inno-usb2: remove redundant assignment to variable delay
Variable delay is being assigned to zero and the code falls through to
the next case in a switch statement that returns out of the function.
The variable is never read in this scenario and so the assignment is
redundant and can be removed.

Cleans up scan-build static analysis warning:
drivers/phy/rockchip/phy-rockchip-inno-usb2.c:753:3: warning: Value

f199223cb4 phy: qcom: Introduce new eDP PHY driver
Many recent Qualcomm platforms comes with native DP and eDP support.
This consists of a controller in the MDSS and a QMP-like PHY.

While similar to the well known QMP block, the eDP PHY only has TX lanes
and the programming sequences are slightly different. Rather than
continuing the trend of parameterize the QMP driver to pieces, this
introduces the support as a new driver.

The registration of link and pixel clocks are borrowed from the QMP
driver. The non-DP link frequencies are omitted for now.

The eDP PHY is very similar to the dedicated (non-USB) DP PHY, but only
the prior is supported for now.

dee2b702bc kconfig: Add support for -Wimplicit-fallthrough
Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang.

The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH,
which is enabled by default.

Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This
bugfix only appears in Clang 14.0.0, so older versions still contain
the bug and -Wimplicit-fallthrough won't be enabled for them, for now.

This concludes a long journey and now we are finally getting rid
of the unintentional fallthrough bug-class in the kernel, entirely. :)

Merge tag 'xfs-5.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs cleanups from Darrick Wong:
 "The most 'exciting' aspect of this branch is that the xfsprogs
  maintainer and I have worked through the last of the code
  discrepancies between kernel and userspace libxfs such that there are
  no code differences between the two except for #includes.

  IOWs, diff suffices to demonstrate that the userspace tools behave the
  same as the kernel, and kernel-only bits are clearly marked in the
  /kernel/ source code instead of just the userspace source.

  Summary:

   - Clean up open-coded swap() calls.

   - A little bit of #ifdef golf to complete the reunification of the
     kernel and userspace libxfs source code"

c36e33e2f4 A set of fixes for the interrupt subsystem:
- Core code:
 
     A regression fix for the Open Firmware interrupt mapping code where a
     interrupt controller property in a node caused a map property in the
     same node to be ignored.
 
   - Interrupt chip drivers:
 
     - Workaround a limitation in SiFive PLIC interrupt chip which silently
       ignores an EOI when the interrupt line is masked.
 
     - Provide the missing mask/unmask implementation for the CSKY MP
       interrupt controller.
 
   - PCI/MSI:
 
     - Prevent a use after free when PCI/MSI interrupts are released by
       destroying the sysfs entries before freeing the memory which is
       accessed in the sysfs show() function.
 
     - Implement a mask quirk for the Nvidia ION AHCI chip which does not
       advertise masking capability despite implementing it. Even worse the
       chip comes out of reset with all MSI entries masked, which due to the
       missing masking capability never get unmasked.
 
     - Move the check which prevents accessing the MSI[X] masking for XEN
       back into the low level accessors. The recent consolidation missed
       that these accessors can be invoked from places which do not have
       that check which broke XEN. Move them back to he original place
       instead of sprinkling tons of these checks all over the code.
