Subject: [PATCH] usb: dwc3: keep susphy enabled during exit to avoid
controller faults
On some platforms, switching USB roles from host to device can trigger
controller faults due to premature PHY power-down. This occurs when the
PHY is disabled too early during teardown, causing synchronization
issues between the PHY and controller.
Keep susphy enabled during dwc3_host_exit() and dwc3_gadget_exit()
ensures the PHY remains in a low-power state capable of handling
required commands during role switch.

Subject: [PATCH] mptcp: pm: ignore unknown endpoint flags
Before this patch, the kernel was saving any flags set by the userspace,
even unknown ones. This doesn't cause critical issues because the kernel
is only looking at specific ones. But on the other hand, endpoints dumps
could tell the userspace some recent flags seem to be supported on older
kernel versions.
Instead, ignore all unknown flags when parsing them. By doing that, the
userspace can continue to set unsupported flags, but it has a way to
verify what is supported by the kernel.
Note that it sounds better to continue accepting unsupported flags not
to change the behaviour, but also that eases things on the userspace
side by adding "optional" endpoint types only supported by newer kernel
versions without having to deal with the different kernel versions.
A note for the backports: there will be conflicts in mptcp.h on older
versions not having the mentioned flags, the new line should still be
added last, and the '5' needs to be adapted to have the same value as
the last entry.
