The tree1 and tree2 variables are initialized earlier in

f931a5d37a kconfig: gconf: remove unnecessary gtk_set_locale() call
gtk_set_locale() has been deprecated since version 2.24, and setlocale()
should be used directly. [1]

However, gtk_init() automatically does this, so there is typically no
point in calling this function.

c22f056e49 net: usb: lan78xx: fix possible NULL pointer dereference in lan78xx_phy_init()
If no PHY device is found (e.g., for LAN7801 in fixed-link mode),
lan78xx_phy_init() may proceed to dereference a NULL phydev pointer,
leading to a crash.

Update the logic to perform MAC configuration first, then check for the presence
of a PHY. For the fixed-link case, set up the fixed link and return early,
bypassing any code that assumes a valid phydev pointer.

It is safe to move lan78xx_mac_prepare_for_phy() earlier because this function
only uses information from dev->interface, which is configured by
lan78xx_get_phy() beforehand. The function does not access phydev or any data
set up by later steps.

b75e1f0619 device property: Use tidy for_each_named_* macros
Implementing if-conditions inside for_each_x() macros requires some
thinking to avoid side effects in the calling code. Resulting code
may look somewhat awkward, and there are couple of different ways it is
usually done.

Standardizing this to one way can help making it more obvious for a code
reader and writer. The newly added for_each_if() is a way to achieve this.

Use for_each_if() to make these macros look like many others which
should in the long run help reading the code.

12c409aa1e pps: fix poll support
Because pps_cdev_poll() returns unconditionally EPOLLIN,
a user space program that calls select/poll get always an immediate data
ready-to-read response. As a result the intended use to wait until next
data becomes ready does not work.

User space snippet:

    struct pollfd pollfd = {
      .fd = open("/dev/pps0", O_RDONLY),
      .events = POLLIN|POLLERR,
      .revents = 0 };
    while(1) {
      poll(&pollfd, 1, 2000/*ms*/); // returns immediate, but should wait
      if(revents & EPOLLIN) { // always true
        struct pps_fdata fdata;
        memset(&fdata, 0, sizeof(memdata));
        ioctl(PPS_FETCH, &fdata); // currently fetches data at max speed
      }
    }

Lets remember the last fetch event counter and compare this value
in pps_cdev_poll() with most recent event counter
and return 0 if they are equal.

6bca1e9558 pps: clients: gpio: fix interrupt handling order in remove path
The interrupt handler in pps_gpio_probe() is registered after calling
pps_register_source() using devm_request_irq(). However, in the
corresponding remove function, pps_unregister_source() is called before
the IRQ is freed, since devm-managed resources are released after the
remove function completes.

This creates a potential race condition where an interrupt may occur
after the PPS source is unregistered but before the handler is removed,
possibly leading to a kernel panic.

To prevent this, switch from devm-managed IRQ registration to manual
management by using request_irq() and calling free_irq() explicitly in
the remove path before unregistering the PPS source. This ensures the
interrupt handler is safely removed before deactivating the PPS source.

bfb4cf9fb9 vmci: Prevent the dispatching of uninitialized payloads
The reproducer executes the host's unlocked_ioctl call in two different
tasks. When init_context fails, the struct vmci_event_ctx is not fully
initialized when executing vmci_datagram_dispatch() to send events to all
vm contexts. This affects the datagram taken from the datagram queue of
its context by another task, because the datagram payload is not initialized
according to the size payload_size, which causes the kernel data to leak
to the user space.

Before dispatching the datagram, and before setting the payload content,
explicitly set the payload content to 0 to avoid data leakage caused by
incomplete payload initialization.

12853b2791 drm/mipi-dsi: Drop MIPI_DSI_MODE_VSYNC_FLUSH flag
Drop the unused MIPI_DSI_MODE_VSYNC_FLUSH flag. Whether or not a display
FIFO flush on vsync is required to avoid sending garbage to the panel is
not a property of the DSI link, but of the integration between display
controller and DSI host bridge.

a36c533ad3 drm/bridge: samsung-dsim: Always flush display FIFO on vsync pulse
Always flush the display FIFO on vsync pulse, even if not explicitly
requested by the panel via MIPI_DSI_MODE_VSYNC_FLUSH mode_flag.

The display FIFO should be empty at vsync. Flushing it at vsync pulses
helps to remove garbage that may have entered the FIFO during startup
(if synchronisation between upstream display controller and Samsung DSIM
is lacking) and that may persist in form of last frame's leftovers on
subsequent frames. Flushing the display FIFO if it is already empty
should have no effect.

This will allow to remove the MIPI_DSI_MODE_VSYNC_FLUSH flag, which is
only used by the Samsung DSIM bridge driver. Arguably this flag doesn't
belong in the panel configuration at all: flushing the display FIFO on
vsync is a workaround for issues with the integration between display
controller and DSI bridge, not a property of the DSI link between bridge
and panel. No panel actually has a requirement to receive garbage or old
frame content after vsync.

I wonder if host controller FIFO resets are mentioned by the MIPI DSI
specification at all. This patch is based on the assumption that the
MIPI_DSI_MODE_VSYNC_FLUSH flag only exists because the DSIM_MFLUSH_VS
bit happens to be located in the same register as the bits controlling
the DSI mode.

1d99f92f71 reset: brcmstb: Enable reset drivers for ARCH_BCM2835
The BRCMSTB and BRCMSTB_RESCAL reset drivers are also
used in the BCM2712, AKA the RPi5. The RPi platforms
have typically used the ARCH_BCM2835, and the PCIe
support for this SoC can use this config which depends
on these drivers so enable building them when just that
arch option is enabled to ensure the platform works as
expected.

DEFINE_RES_*() are compound literals, and hence no need to do that explicitly.
Besides that, we have no IRQ name provided, no need to use _NAMED() variant.
Replace open coded variant of DEFINE_RES_IRQ().
