+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.
+
+Fixes: 553a3ac ("ath10k-ct: use 5.15 version")
