Bug#956858: firmware-b43-installer.postinst returns with error

[oetzy <mgspam@web.de>]

Package: firmware-b43-installer
Version: 1:019-5
Severity: normal

Dear Maintainer,

during update to the latest version 1:019-5, firmware-b43-installer.postinst returned with an error while trying to delete the old firmware.
/var/lib/dpkg/info/firmware-b43-installer.postinst: Deleting old extracted firmware...
rm: Removing '/lib/firmware/b43/lp0initvals14.fw' is not possible. File or directory not found.
[snip a lot more errors]

As a result, the firmware could not be loaded during boot.

It seems that, for whatever reason, /lib/firmware/b43 was left behind with only the file 'firmware-b43-installer.catalog' in it during the update.
This caused the postinst script to return with the  error code 123 when trying to remove the old, non-existing firmware files.
Removing (renaming) /lib/firmware/b43 and re-installing firmware-b43-installer fixed the problem.
