Subject: MIPS: sead3: use unflatten_and_copy_device_tree()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e8a2762dcdcc271656c4333848d6d796c3f5a42;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

MIPS: sead3: use unflatten_and_copy_device_tree()

we want the device tree to be unflattened into non init memory so it can be
accessed later by, for example, a probing function of a driver module.
