[PATCH] libertas: Don't mark exported symbols as static

[Roland Dreier]

Marking exported symbols as static causes the following build error on
ia64 with gcc 4.2.3:

drivers/net/wireless/libertas/main.c:1375: error: __ksymtab_lbs_remove_mesh causes a section type conflict
drivers/net/wireless/libertas/main.c:1354: error: __ksymtab_lbs_add_mesh causes a section type conflict

Therefore, remove the static marking on lbs_remove_mesh and lbs_add_mesh.

Why not pull the exports? they aren't used anywhere in the existing kernel.

I'm guessing there's some not-(yet-)merged mesh networking stuff that
uses the symbols, but it doesn't matter much to me...

The general rule is to not keep symbols for out of tree stuff, so
removing the exports makes more sense.

If they aren't used in the in-kernel driver, just kill the export
statements.

[PATCH] libertas: Remove unused exports

[Roland Dreier]

The libertas driver exports a number of symbols with no in-tree
users; remove these unused exports.  lbs_reset_device() is completely
unused, with no callers at all, so remove the function completely.

A couple of these unused exported symbols are static, which causes the
following build error on ia64 with gcc 4.2.3:

    drivers/net/wireless/libertas/main.c:1375: error: __ksymtab_lbs_remove_mesh causes a section type conflict
    drivers/net/wireless/libertas/main.c:1354: error: __ksymtab_lbs_add_mesh causes a section type conflict

This patch fixes this problem.  I don't have hardware, so this is not
run-tested, but I tested the build with

    CONFIG_LIBERTAS=y
    CONFIG_LIBERTAS_USB=m
    CONFIG_LIBERTAS_CS=m
    CONFIG_LIBERTAS_SDIO=m

and there were no problems with undefined symbols.

[PATCH RESEND] libertas: Remove unused exports

Any chance of getting this applied?  It seems the build is still
broken on ia64 at least due to the export of static functions.

The libertas driver exports a number of symbols with no in-tree
users; remove these unused exports.  lbs_reset_device() is completely

However; if the symbols aren't used anywhere in
drivers/net/wireless/libertas/*, it makes no sense to keep them around &
exported.
