In the Linux kernel, the following vulnerability has been resolved:
iio: adc: adi-axi-adc: Fix refcount leak in adi_axi_adc_attach_client
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

In the Linux kernel, the following vulnerability has been resolved:
net: phy: at803x: fix NULL pointer dereference on AR9331 PHY
Latest kernel will explode on the PHY interrupt config, since it depends
now on allocated priv. So, run probe to allocate priv to fix it.
ar9331_switch ethernet.1:10 lan0 (uninitialized): PHY [!ahb!ethernet@1a000000!mdio!switch@10:00] driver [Qualcomm Atheros AR9331 built-in PHY] (irq=13)
CPU 0 Unable to handle kernel paging request at virtual address 0000000a, epc == 8050e8a8, ra == 80504b34

Same Issue would affect some other PHYs (QCA8081, QCA9561), so fix it
too.

In the Linux kernel, the following vulnerability has been resolved:
RDMA/cm: Fix memory leak in ib_cm_insert_listen
cm_alloc_id_priv() allocates resource for the cm_id_priv. When
cm_init_listen() fails it doesn't free it, leading to memory leak.
Add the missing error unwind.

In the Linux kernel, the following vulnerability has been resolved:
memory: samsung: exynos5422-dmc: Fix refcount leak in of_get_dram_timings
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
This function doesn't call of_node_put() in some error paths.
To unify the structure, Add put_node label and goto it on errors.

In the Linux kernel, the following vulnerability has been resolved:
soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
In brcmstb_init_sram, it pass dn to of_address_to_resource(),
of_address_to_resource() will call of_find_device_by_node() to take
reference, so we should release the reference returned by
of_find_matching_node().
