Subject: [PATCH] firmware: tegra: bpmp: Revert "firmware: tegra: bpmp: Use scoped device node handling to simplify error paths"

This reverts commit 8812b8689ee6 ("firmware: tegra: bpmp: Use scoped
device node handling to simplify error paths") because it was silently
modified by committer during commit process, by moving declaration of
'struct device_node *np' above the initializer/constructor.  Such code
was not intention of the author, is not conforming to cleanup.h code
style and decreases the code readability.

I did not write such code and I did not agree to put my name with such
commit.

Original patch:
https://lore.kernel.org/all/20240816135722.105945-2-krzysztof.kozlowski@linaro.org/

Cc: Arnd Bergmann <arnd@...db.de>
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

It's very strange to see own patches silently modified without any
explanation in Signed-off-by area.
