[PATCH AUTOSEL 6.14 10/54] net: page_pool: don't cast mp param to devmem

[Sasha Levin <sashal@kernel.org>]

From: Pavel Begunkov <asml.silence@gmail.com>

[ Upstream commit 8d522566ae9cb3f0609ddb2a6ce3f4f39988043c ]

page_pool_check_memory_provider() is a generic path and shouldn't assume
anything about the actual type of the memory provider argument. It's
fine while devmem is the only provider, but cast away the devmem
specific binding types to avoid confusion.
