+Subject: iio: imu: adis16400: Fix sign extension
+
+From: Rasmus Villemoes <linux@rasmusvillemoes.dk>
+
+commit 19e353f2b344ad86cea6ebbc0002e5f903480a90 upstream.
+
+The intention is obviously to sign-extend a 12 bit quantity. But
+because of C's promotion rules, the assignment is equivalent to "val16
+&= 0xfff;". Use the proper API for this.
