pci_intx() is a hybrid function which sometimes performs devres operations, depending on whether pcim_enable_device() has been used to enable the pci_dev. This sometimes-managed nature of the function is problematic. Notably, it causes the function to allocate under some circumstances which makes it unusable from interrupt context. Export pcim_intx() (which is always managed) and rename __pcim_intx() (which is never managed) to pci_intx_unmanaged() and export it as well. 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().
