Subject: [PATCH 1/2] spi: spi-cavium-thunderx: Use non-hybrid PCI devres API
Date: Thu, 17 Apr 2025 10:39:02 +0200 [thread overview]
Message-ID: <20250417083902.23483-2-phasta@kernel.org> (raw)
cavium-thunderx enables its PCI device with pcim_enable_device(). This,
implicitly, switches the function pci_request_regions() into managed
mode, where it becomes a devres function.
The PCI subsystem wants to remove this hybrid nature from its
interfaces. To do so, users of the aforementioned combination of
functions must be ported to non-hybrid functions.
Moreover, since both functions are already managed in this driver, the
calls to pci_release_regions() are unnecessary.
Remove the calls to pci_release_regions().
Replace the call to sometimes-managed pci_request_regions() with one to
the always-managed pcim_request_all_regions().
