This patch backports the interface of the b43 and b43legacy driver from
|
|
the new to the old ssb API. This patch is needed as long the old ssb
|
|
version is used in the kernel for broadcom devices. After upgrading to
|
|
ssb version out of kernel 2.6.27 or later this patch is not needed any more.
