Subject: [PATCH] libertas: remove adapter->{rx,tx}antenna
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fdde7084e033263f48d26d5b24ecf626aed29b5b;p=linux-beck.git

[PATCH] libertas: remove adapter->{rx,tx}antenna

There was nowhere any code that used the values of those
variables.

This patch also removes two static functions that are now unused.
