| Subject: ath9k_hw: Fix number of GPIO pins for AR9287/9300 |
| |
| From: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> |
| |
| commit 6321eb0977b011ac61dfca36e7c69b2c4325b104 upstream. |
| |
| this patch fixes the assumption of maximum number of GPIO pins present |
| in AR9287/AR9300. this fix is essential as we might encounter some |
| functionality issues involved in accessing the status of GPIO pins which |
| are all incorrectly assumed to be not within the range of max_num_gpio |
| of AR9300/AR9287 chipsets |
