crypto: artpec6 - Simplify with of_device_get_match_data()

2025-11-14T10:15:48+00:00

Driver's probe function matches against driver's of_device_id table, so of_match_node() can be simplified with of_device_get_match_data(). This requires changing the enum used in the driver match data entries to non-zero, to be able to recognize error case of of_device_get_match_data().

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37+00:00

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

crypto: artpec6 - change from kzalloc to kcalloc in artpec6_crypto_probe()

2025-03-15T08:21:22+00:00

We are trying to get rid of all multiplications from allocation functions to prevent potential integer overflows. Here the multiplication is probably safe, but using kcalloc() is more appropriate and improves readability. This patch has no effect on runtime behavior.

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: axis - Remove unused struct 'dbgfs_u32'

2024-05-31T09:34:56+00:00

'dbgfs_u32' appears unused. Remove it. (pdma_stat_descr is also unused, but I'm assuming it's some useful layout description of firmware/hardware so best left in) Signed-off-by: Dr. David Alan Gilbert Acked-by: Jesper Nilsson Signed-off-by: Herbert Xu

crypto: artpec6 - Use helper to set reqsize

crypto: artpec6 - stop setting alignmask for ahashes

2023-10-27T10:04:28+00:00

The crypto API's support for alignmasks for ahash algorithms is nearly useless, as its only effect is to cause the API to align the key and result buffers. The drivers that happen to be specifying an alignmask for ahash rarely actually need it. When they do, it's easily fixable, especially considering that these buffers cannot be used for DMA. In preparation for removing alignmask support from ahash, this patch makes the artpec6 driver no longer use it. This driver is unusual in that it DMAs the digest directly to the result buffer. This is broken because the crypto API provides the result buffer as an arbitrary virtual address, which might not be valid for DMA, even after the crypto API applies the alignmask. Maybe the alignmask (which this driver set only to 3) made this code work in a few more cases than it otherwise would have. But even if so, it doesn't make sense for this single driver that is broken anyway to block removal of the alignmask support. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: axis/artpec6 - Convert to platform remove callback returning void

2023-10-27T10:04:25+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 Acked-by: Jesper Nilsson Signed-off-by: Herbert Xu
