| Subject: iwlwifi: dvm: fix zero LQ CMD sending avoidance |
| |
| From: Emmanuel Grumbach <emmanuel.grumbach@intel.com> |
| |
| commit a87783699b23395c46bbeeb5d28f6db24897bf26 upstream. |
| |
| In 63b77bf489881747c5118476918cc8c29378ee63 |
| |
| iwlwifi: dvm: don't send zeroed LQ cmd |
| |
| I tried to avoid to send zeroed LQ cmd, but I made a (very) |
| stupid mistake in the memcmp. |
| Since this patch has been ported to stable, the fix should |
| go to stable too. |
| |
| This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58341 |
