| Subject: iwlwifi: pcie: fix prph dump length |
| |
| From: Liad Kaufman <liad.kaufman@intel.com> |
| |
| commit 87dd634ae72bb8f6d0dd12f1cbbc67c7da6dba3b upstream. |
| |
| The length counting previously done had an error in it, causing |
| the length down the data dumping function to be shorter than it |
| should be, causing the end of the data to get truncated off and |
| lost. |
| |
| Fixes: 67c65f2cf710 ("iwlwifi: dump periphery registers to fw-error-dump") |
