crypto: omap - Use sysfs_emit in sysfs show functions

2026-01-30T08:09:32+00:00

Replace sprintf() with sysfs_emit() in sysfs show functions. sysfs_emit() is preferred to format sysfs output as it provides better bounds checking. No functional changes. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

crypto: omap - convert from tasklet to BH workqueue

2025-09-13T04:11:06+00:00

tasklet has been marked deprecated and it's planned to be removed. Make omap crypto drivers to use BH workqueue which is the new interface for executing in BH context in place of tasklet. Signed-off-by: Ryo Takakura Acked-by: Tejun Heo Signed-off-by: Herbert Xu

crypto: drivers - Remove redundant pm_runtime_mark_last_busy() calls

2025-07-18T10:51:59+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy(). Signed-off-by: Sakari Ailus Signed-off-by: Herbert Xu

crypto: omap-aes - use dev_groups to register attribute groups

2025-04-07T05:22:26+00:00

Instead of manually adding attribute groups, set dev_groups pointer to have the driver core do it. Signed-off-by: Ovidiu Panait Signed-off-by: Herbert Xu

crypto: omap - switch from scatter_walk to plain offset

2025-01-14T03:38:32+00:00

The omap driver was using struct scatter_walk, but only to maintain an offset, rather than iterating through the virtual addresses of the data contained in the scatterlist which is what scatter_walk is intended for. Make it just use a plain offset instead. This is simpler and avoids using struct scatter_walk in a way that is not well supported. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: drivers - Switch back to struct platform_driver::remove()

2024-10-19T00:44:30+00:00

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.

crypto: omap-aes - Convert to platform remove callback returning void

2023-10-27T10:04:26+00:00

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. Signed-off-by: Uwe Kleine-König Signed-off-by: Herbert Xu

crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

crypto: omap - Use new crypto_engine_op interface

2023-08-18T09:01:11+00:00

Use the new crypto_engine_op interface where the callback is stored in the algorithm object. Signed-off-by: Herbert Xu

crypto: omap - Include internal/engine.h

2023-08-18T09:01:10+00:00

Inlucde internal/engine.h because this driver uses directly accesses attributes inside struct crypto_engine. Signed-off-by: Herbert Xu
