+Subject: iio: light: isl29028: Fix the warning in isl29028_remove()
+
+From: Zheyu Ma <zheyuma97@gmail.com>
+
+commit 06674fc7c003b9d0aa1d37fef7ab2c24802cc6ad upstream.
+
+The driver use the non-managed form of the register function in
+isl29028_remove(). To keep the release order as mirroring the ordering
+in probe, the driver should use non-managed form in probe, too.
+
+The following log reveals it:
+
