   4 Subject: [PATCH] mwlwifi: replace get/set_fs() calls
   5
   6 Since kernel 5.9 the get/set_fs() call implementation have started to get
   7 dropped from individual architectures, ARM64 one got dropped in 5.11.
   8
   9 Replace the get/set_fs() calls with force_uaccess_begin/end() to allow
  10 compiling on newer kernels.
  11 There is no need to add kernel version checks as the replacement functions
  12 are available since kernel 5.9.
