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.
