+Subject: [PATCH 695/782] i2c: bcm2835: Move IRQ request after clock code in
+ probe
+
+Commit 4a5cfa39465cad25dd736d7ceba8a5d32eea4ecc upstream.
+
+If any of the clock code in the probe fails and returns, the IRQ
+will not be freed.  Moving the IRQ request to last allows it to
+be freed on any errors further up in the probe function.  devm_
+calls can apparently not be used because there are some potential
+race conditions that will arise.
+
+Fixes: bebff81fb8b9 ("i2c: bcm2835: Model Divider in CCF")
