| Subject: ath9k: Clear key cache explicitly on disabling hardware |
| |
| From: Jouni Malinen <jouni@codeaurora.org> |
| |
| commit 73488cb2fa3bb1ef9f6cf0d757f76958bd4deaca upstream. |
| |
| Now that ath/key.c may not be explicitly clearing keys from the key |
| cache, clear all key cache entries when disabling hardware to make sure |
| no keys are left behind beyond this point. |
