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