ath9k_htc: memory corruption calling set_bit()
In d8a2c51cdcae ('ath9k_htc: Use atomic operations for op_flags') we
changed things like this:
- if (priv->op_flags & OP_TSF_RESET) {
+ if (test_bit(OP_TSF_RESET, &priv->op_flags)) {
The problem is that test_bit() takes a bit number and not a mask. It
means that when we do:
set_bit(OP_TSF_RESET, &priv->op_flags);
Then it sets the (1 << 6) bit instead of the 6 bit so we are setting a
bit which is past the end of the unsigned long.
Fixes: d8a2c51cdcae ('ath9k_htc: Use atomic operations for op_flags')
