pci_intx() is a hybrid function which sometimes performs devres

problematic. Notably, it causes the function to allocate under some
circumstances which makes it unusable from interrupt context.

To, ultimately, remove the hybrid nature from pci_intx(), it is first
necessary to provide an always-managed and a never-managed version
of that function. Then, all callers of pci_intx() can be ported to the
version they need, depending whether they use pci_enable_device() or
pcim_enable_device().

An always-managed function exists, namely pcim_intx(), for which
__pcim_intx(), a never-managed version of pci_intx() had been

s/had/has ? Not sure about this, English is not my first language :)

implemented.

Make __pcim_intx() a public function under the name
pci_intx_unmanaged(). Make pcim_intx() a public function.

Regardless of the above nit, looks OK to me.
