The function calls of_parse_phandle() to get a
device node, which increments the reference count of the node. However,
the function fails to call of_node_put() to decrement the reference.
This leads to a reference count leak.
This is found by static analysis and similar to the commit a508e33956b5
("ipmi:ipmb: Fix refcount leak in ipmi_ipmb_probe")

From: Emanuele Ghidoli <emanuele.ghidoli(a)toradex.com>
While the DP83867 PHYs report EEE capability through their feature
registers, the actual hardware does not support EEE (see Links).
When the connected MAC enables EEE, it causes link instability and
communication failures.
The issue is reproducible with a iMX8MP and relevant stmmac ethernet port.
Since the introduction of phylink-managed EEE support in the stmmac driver,
EEE is now enabled by default, leading to issues on systems using the
DP83867 PHY.
Call phy_disable_eee during phy initialization to prevent EEE from being
enabled on DP83867 PHYs.

Subject: [PATCH] serial: 8250_dw: handle reset control deassert error
Check the return value of reset_control_deassert() in the probe
function to prevent continuing probe when reset deassertion fails.
Previously, reset_control_deassert() was called without checking its
return value, which could lead to probe continuing even when the
device reset wasn't properly deasserted.
The fix checks the return value and returns an error with dev_err_probe()
if reset deassertion fails, providing better error handling and
diagnostics.

A maximum gain of 0xffff / 65525 seems unlikely and testing indeed shows
that the gain control wraps-around at 4096, so set the maximum gain to
0xfff / 4095.
The minimum gain of 0x100 is correct. Setting bits 8-11 to 0x0 results
in the same gain values as setting these bits to 0x1, with bits 0-7
still increasing the gain when going from 0x000 - 0x0ff in the exact
same range as when going from 0x100 - 0x1ff.

During sensor calibration I noticed that with the hflip control set
to false/disabled the image was mirrored.
So it seems that the horizontal flip control is inverted and needs to
be set to 1 to not flip (just like the similar problem recently fixed
on the ov08x40 sensor).
Invert the hflip control to fix the sensor mirroring by default.
As the comment above the newly added OV01A10_MEDIA_BUS_FMT define explains
the control being inverted also means that the native Bayer-order of
the sensor actually is GBRG not BGGR, but so as to not break userspace
the Bayer-order is kept at BGGR.

Subject: [PATCH] xhci: dbc: fix bogus 1024 byte prefix if ttyDBC read races
with stall event
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
DbC may add 1024 bogus bytes to the beginneing of the receiving endpoint
if DbC hw triggers a STALL event before any Transfer Blocks (TRBs) for
incoming data are queued, but driver handles the event after it queued
the TRBs.
This is possible as xHCI DbC hardware may trigger spurious STALL transfer
events even if endpoint is empty. The STALL event contains a pointer
to the stalled TRB, and "remaining" untransferred data length.
As there are no TRBs queued yet the STALL event will just point to first
TRB position of the empty ring, with '0' bytes remaining untransferred.
DbC driver is polling for events, and may not handle the STALL event
before /dev/ttyDBC0 is opened and incoming data TRBs are queued.
The DbC event handler will now assume the first queued TRB (length 1024)
has stalled with '0' bytes remaining untransferred, and copies the data
This race situation can be practically mitigated by making sure the event
handler handles all pending transfer events when DbC reaches configured
state, and only then create dev/ttyDbC0, and start queueing transfers.
The event handler can this way detect the STALL events on empty rings
and discard them before any transfers are queued.
This does in practice solve the issue, but still leaves a small possible
gap for the race to trigger.
We still need a way to distinguish spurious STALLs on empty rings with '0'
bytes remaing, from actual STALL events with all bytes transmitted.
