[patch 06/58] b43: fix b43_plcp_get_bitrate_idx_ofdm return type

[Greg KH]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Lorenzo Nava <navalorenx@xxxxxxxxx>

upstream commit: a3c0b87c4f21911fb7185902dd13f0e3cd7f33f7

This patch fixes the return type of b43_plcp_get_bitrate_idx_ofdm. If
the plcp contains an error, the function return value is 255 instead
of -1, and the packet was not dropped. This causes a warning in
__ieee80211_rx function because rate idx is out of range.
