3.6.11.5 stable review patch. If anyone has any objections, please let me know. ------------------ From: Chen Gang [ Upstream commit 2c1bbbffa0b644fab4f91878cde0c2e8f52e2dcc ] Change MAC802154_CHAN_NONE from ~(u8)0 to 0xff, or the comparison in mac802154_wpan_xmit() for ``chan == MAC802154_CHAN_NONE'' will not succeed. This bug can be boiled down to ``u8 foo = 0xff; if (foo == ~(u8)0) [...] else [...]'' where the condition will always take the else branch. Signed-off-by: Chen Gang Signed-off-by: David S.
