| Subject: ath9k: Do not assign noise for NULL caldata |
| |
| From: Sujith Manoharan <c_manoha@qca.qualcomm.com> |
| |
| commit d3bcb7b24bbf09fde8405770e676fe0c11c79662 upstream. |
| |
| ah->noise is maintained globally and not per-channel. This |
| is updated in the reset() routine after the NF history has been |
| filled for the *current channel*, just before switching to |
| the new channel. There is no need to do it inside getnf(), since |
| ah->noise must contain a value for the new channel. |
