-Subject: [PATCH 696/773] 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.
-
