2024-10-19crypto: drivers - Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/crypto to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2023-10-27crypto: aspeed-hace - Convert to platform remove callback returning voidUwe Kleine-König
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.

2023-10-13crypto: aspeed-hace - Use device_get_match_data()Rob Herring
Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers.

2022-09-30crypto: aspeed - Fix check for platform_get_irq() errorsYueHaibing
The platform_get_irq() function returns negative on error and positive non-zero values on success. It never returns zero, but if it did then treat that as a success. Also remove redundant dev_err() print as platform_get_irq() already prints an error.
