+Subject: media: si470x-i2c: Move free() past last use of 'radio'
+To: stable@vger.kernel.org
+Cc: linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org
+Message-ID: <20200203132130.12748-1-lee.jones@linaro.org>
+
+From: Lee Jones <lee.jones@linaro.org>
+
+A pointer to 'struct si470x_device' is currently used after free:
+
+  drivers/media/radio/si470x/radio-si470x-i2c.c:462:25-30: ERROR: reference
+    preceded by free on line 460
+
+Shift the call to free() down past its final use.
+
+NB: Not sending to Mainline, since the problem does not exist there, it was
+caused by the backport of 2df200ab234a ("media: si470x-i2c: add missed
+operations in remove") to the stable trees.
