   4 Subject: [PATCH] ath10k-ct: Fix spectral scan NULL pointer
   5
   6 If spectral scan support is enabled then ath10k-ct will cause a NULL
   7 pointer due to relay_open() being called with a const callback struct
   8 which is only supported in kernel 5.11 and later.
   9
  10 So, simply check the kernel version and if 5.11 and newer use the const
  11 callback struct, otherwise use the regular struct.
  12
  13 Fixes: 553a3ac ("ath10k-ct: use 5.15 version")
