From 770847bad0200b62af2d93808b4e69d82f14264e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Sun, 12 Jul 2015 18:11:46 -0500 Subject: MIPS: Remove "weak" from get_c0_fdc_int() declaration Weak header file declarations are error-prone because they make every definition weak, and the linker chooses one based on link order (see 10629d711ed7 ("PCI: Remove __weak annotation from pcibios_get_phb_of_node decl")). The most elegant solution is to have a weak default implementation and allow a strong function to override it. Then we don't have to test whether a definition is present, and if there are ever multiple strong definitions, we get a link error instead of calling a random definition. Add a weak get_c0_fdc_int() definition with the default code and remove the weak annotation from the declaration.
