linux-next: manual merge of the tegra tree with the origin tree

linux-next: manual merge of the tegra tree with the origin tree

Hi all,

Today's linux-next merge of the tegra tree got a conflict in:

  drivers/firmware/tegra/bpmp-tegra210.c

between commit:

  4dd10fbbeb9c3 ("treewide: Convert devm_kmalloc() family to the devm_kmalloc_obj() family")

from the origin tree and commit:

  ee98ea41ee3fb ("firmware: tegra: bpmp: Add ACPI support")

from the tegra tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Hi all,
