[PATCH 0/2] ARM: mstar: fix two device_node refcount leaks in mstarv7.c

[Weigang He <geoffreyhe2@gmail.com>]

mstarv7.c leaks the device_node reference taken by
of_find_compatible_node() in two __init paths: mstarv7_boot_secondary()
(the "mstar,smpctrl" node) and mstarv7_init() (the "mstar,l3bridge"
node). of_iomap() does not take ownership of the node, so each is a
one-shot device_node refcount leak per boot.

The two leaks were introduced by different commits, so they are split
into one patch each. Both drop the reference right after of_iomap().

Found by static analysis tool CodeQL. The series is build-tested only
(arm, multi_v7_defconfig + CONFIG_ARCH_MSTARV7); I have no mstar
hardware, so runtime testing would be appreciated.
