+Subject: hwmon: (dell-smm) Fix warning on /proc/i8k creation error
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+commit dbd3e6eaf3d813939b28e8a66e29d81cdc836445 upstream.
+
+The removal function is called regardless of whether
+/proc/i8k was created successfully or not, the later
+causing a WARN() on module removal.
+Fix that by only registering the removal function
+if /proc/i8k was created successfully.
+
+Tested on a Inspiron 3505.
+
+Fixes: 039ae58503f3 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k")
