[PATCH 1/2] i2c: ismt: Use non-hybrid PCI devres API

From: Philipp Stanner
Date: Thu Apr 17 2025 - 04:25:29 EST


ismt enables its PCI device with pcim_enable_device(). This,
implicitly, switches the function pci_request_region() 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.

Replace the call to sometimes-managed pci_request_region() with one to
the always-managed pcim_request_region().
