#     PCI: rpaphp: Avoid a sometimes-uninitialized warning
#     
#     When building with -Wsometimes-uninitialized, clang warns:
#     
#     drivers/pci/hotplug/rpaphp_core.c:243:14: warning: variable 'fndit' is
#     used uninitialized whenever 'for' loop exits because its condition is
#     false [-Wsometimes-uninitialized]
#             for (j = 0; j < entries; j++) {
#                         ^~~~~~~~~~~
#     drivers/pci/hotplug/rpaphp_core.c:256:6: note: uninitialized use occurs
#     here
#             if (fndit)
#                 ^~~~~
#     drivers/pci/hotplug/rpaphp_core.c:243:14: note: remove the condition if
#     it is always true
#             for (j = 0; j < entries; j++) {
#                         ^~~~~~~~~~~
#     drivers/pci/hotplug/rpaphp_core.c:233:14: note: initialize the variable
#     'fndit' to silence this warning
#             int j, fndit;
#                         ^
#                          = 0
#     
#     fndit is only used to gate a sprintf call, which can be moved into the
#     loop to simplify the code and eliminate the local variable, which will
#     fix this warning.
#

WARNING: vmlinux.o(.text+0x31fc): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init()
The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.

WARNING: vmlinux.o(.text+0x33d0): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
