| Subject: [PATCH] staging: vt6656: fix sign of rx_dbm to bb_pre_ed_rssi. |
| |
| commit 93134df520f23f4e9998c425b8987edca7016817 upstream. |
| |
| bb_pre_ed_rssi is an u8 rx_dm always returns negative signed |
| values add minus operator to always yield positive. |
| |
| fixes issue where rx sensitivity is always set to maximum because |
| the unsigned numbers were always greater then 100. |
| |
| Fixes: 63b9907f58f1 ("staging: vt6656: mac80211 conversion: create rx function.") |
