linux-next: build warnings after merge of the moduleh tree

linux-next: build warnings after merge of the moduleh tree

[Stephen Rothwell]

Hi Paul,

After merging the moduleh tree, today's linux-next build (x86_64
allmodconfig) produced these warnings:

drivers/net/wireless/brcm80211/brcmutil/wifi.c:43:1: warning: data definition has no type or storage class [enabled by default]

Caused by commit 5b435de0d786 ("net: wireless: add brcm80211 drivers")
from the wireless tree interacting with the module.h split up.

I have added the following patch:

Thanks Stephen, added to the post merge queue with the other post-merge
wireless export.h additions.

I will carry it for now (as a merge fixup on the moduleh tree.  If the
export.h split goes to Linus, then Neil can apply it to his tree, or
Linus can apply it as a merge fixup ehen he merges the latter of the two
trees (as long as someone remember to tell him).

This one is a bit more interesting.  The above files (and actually their
parent dir) doesn't exist yet in master/HEAD.  So I can't patch them
yet.  And the MD maintainers can't patch in export.h usage, since they
won't have such a header file.

If you didn't want to temporarily carry it, I can think of two things:
I suppose, since the one single commit that creates export.h is totally
standalone, and harmless/inert in itself, we could perhaps get it pulled
independently if it made life easier for others to align to the right
usage?  Or they can just patch in module.h usage and we can downgrade
them to export.h usage shortly thereafter.

linux-next: build warnings after merge of the moduleh tree

[Stephen Rothwell]

Hi Paul,

After merging the moduleh tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:

drivers/of/of_pci_irq.c:92:1: warning: data definition has no type or storage class
drivers/of/of_pci_irq.c:92:1: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL'
drivers/of/of_pci_irq.c:92:1: warning: parameter names (without types) in function declaration

This is an interaction with commit 98d9f30c820d ("pci/of: Match PCI
devices to OF nodes dynamically") which split off part of
drivers/of/of_pci.c.

I have added this patch for today:
