[PATCH] obsolete in kernel source (B43_LEGACY_RFKILL)

[Christoph Egger <siccegge@stud.informatik.uni-erlangen.de>]

[-- Attachment #1: Type: text/plain, Size: 646 bytes --]

Hi all!

	As part of the VAMOS[0] research project at the University of
Erlangen we're checking referential integrity between kernel KConfig
options and in-code Conditional blocks.

	While the config option B43_LEGACY_RFKILL was dropped when the
driver's rfkill facility was ported to cfg80211 in [2] it is still
referenced for debug output in [1] probably we just want to get rid of
it.

	Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

Regards

	Christoph Egger

Subject: [PATCH] Remove config option B43_LEGACY_RFKILL completely

In f41f3f373dd72344c65d801d6381fe83ef3a2c54 the B43 driver was ported
to use the cfg80211 API for rfkill and consequently the config option
was dropped (RFKILL is now unconditionally enabled).

However in the Kernel Info the feature is still checked and reported
missing. This patch just removes the conditional and the relevant code
blocks while still reporting that feature unconditionally would be
another option (it's always there).
