- Subject: [PATCH 35/42] thermal: lvts: Convert to platform remove callback
- returning void
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- The .remove() callback for a platform driver returns an int which makes
- many driver authors wrongly assume it's possible to do error handling by
- returning an error code. However the value returned is ignored (apart
- from emitting a warning) and this typically results in resource leaks.
- To improve here there is a quest to make the remove callback return
- void. In the first step of this quest all drivers are converted to
- .remove_new(), which already returns void. Eventually after all drivers
- are converted, .remove_new() will be renamed to .remove().
- Trivially convert this driver from always returning zero in the remove
- callback to the void returning variant.
