b43 is broken

b43 fails to load if linux-backports-modules-cw-3.12-precise-generic is installed:

ojab, thank you for reporting this and helping make Ubuntu better.

Just to clarify, in your Bug Description the package linux-backports-modules-cw-3.12-precise-generic is not installed. Hence, were you just showing us the package version that if it was installed correlates to this issue?

[ojab (ojab)]

Yeah, on the moment of bug report I've already deleted it to have wi-fi working.
Before apport-collect I've installed it again & rebooted (and had wi-fi broken again).

Related SSB options from 3.12 config:
CONFIG_B43_SSB=y
CONFIG_SSB_POSSIBLE=y
CONFIG_SSB=m
CONFIG_SSB_SPROM=y
CONFIG_SSB_BLOCKIO=y
CONFIG_SSB_PCIHOST_POSSIBLE=y
CONFIG_SSB_PCIHOST=y
CONFIG_SSB_B43_PCI_BRIDGE=y
CONFIG_SSB_DRIVER_PCICORE_POSSIBLE=y
CONFIG_SSB_DRIVER_PCICORE=y

but updates/cw-3.12/defconfigs/wifi from linux-backports-modules-3.2.0_3.2.0-86.78.tar.gz has only
CONFIG_SSB=m
CONFIG_SSB_PCMCIAHOST=y
CONFIG_SSB_SDIOHOST=y

[ojab (ojab)]

erm, s/CONFIG/CPTCFG/ for updates/cw-3.12/defconfigs/wifi

[ojab (ojab)]

…and actually compiled .config has all needed options enabled, but ssb.ko is not packaged into resulting .deb.

Looking at warnings from build it looks like b43 & brcmsmac is broken in all backports >= 3.7.

[ojab (ojab)]

this fixes build here, looks like the same will also work for cw-3.10 & cw-3.11:

What should be done to have it fixed in repos?
