[PATCH v3 05/11] misc: Use never-managed version of pci_intx()
Posted by Philipp Stanner 1 week, 6 days ago
pci_intx() is a hybrid function which can sometimes be managed through
devres. To remove this hybrid nature from pci_intx(), it is necessary to
port users to either an always-managed or a never-managed version.

cardreader/rtsx_pcr.c and tifm_7xx1.c enable their PCI-Device with
pci_enable_device(). Thus, they need the never-managed version.

Replace pci_intx() with pci_intx_unmanaged().
