-Subject: [PATCH] Get rid of get_fs/set_fs calls in Broadcom WL driver.
-
-Tentative patch for broadcom-wl 6.30.223.271 driver for Linux 5.10 (tested -rc1 up to 5.10.1)
-
-Applies on top of all the patches applied to broadcom-wl-dkms 6.30.223.271-23 on Arch Linux.
-
-NB: Some checks in wlc_ioctl_internal are likely superfluous,
- but I'm not familiar enough with the driver to remove them with confidence.
