+Subject: Get rid of get_fs/set_fs calls in Broadcom WL driver.
+Origin: https://gist.github.com/joanbm/5c640ac074d27fd1d82c74a5b67a1290
+
+Fixes linux-next where get_fs/set_fs is already removed for some architectures.
+
+NB: Some checks in wlc_ioctl_internal are likely superfluous,
+    but I'm not familiar enough with the driver to remove them with confidence.
+
