From 0d2e335d780bda1432a9ba719c8200f796d27854 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Mon, 29 Nov 2021 12:27:12 +0100 Subject: [PATCH] ath10k-ct: Fix spectral scan NULL pointer If spectral scan support is enabled then ath10k-ct will cause a NULL pointer due to relay_open() being called with a const callback struct which is only supported in kernel 5.11 and later. So, simply check the kernel version and if 5.11 and newer use the const callback struct, otherwise use the regular struct.
