crypto: ux500/hash - simplify if-if to if-else

2022-04-15T08:34:28Z

Replace `if (!req_ctx->updated)` with `else` for simplification and add curly brackets according to the kernel coding style: "Do not unnecessarily use braces where a single statement will do." ... "This does not apply if only one branch of a conditional statement is a single statement; in the latter case use braces in both branches" Please refer to: https://www.kernel.org/doc/html/v5.17-rc8/process/coding-style.html Signed-off-by: Yihao Han Signed-off-by: Herbert Xu

crypto: ux500 - use GFP_KERNEL

2022-02-18T05:21:09Z

Platform_driver probe functions aren't called with locks held and thus don't need GFP_ATOMIC. Use GFP_KERNEL instead. Problem found with Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Herbert Xu

crypto: ux500 - Use platform_get_irq() to get the interrupt

2021-12-24T03:18:28Z

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq() so that interrupt mapping is created on demand. While at it also store the IRQ number in struct cryp_device_data so that we don't have to call platform_get_irq() frequently. Signed-off-by: Lad Prabhakar Signed-off-by: Herbert Xu

crypto: ux500 - Fix error return code in hash_hw_final()

2021-05-14T11:07:58Z

Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. Fixes: 8a63b1994c50 ("crypto: ux500 - Add driver for HASH hardware") Reported-by: Hulk Robot Signed-off-by: Zhen Lei Reviewed-by: Linus Walleij Signed-off-by: Herbert Xu

crypto: ux500 - Remove redundant dev_err calls

2021-04-16T11:16:32Z

There is a error message within devm_ioremap_resource already, so remove the dev_err call to avoid redundant error message. Signed-off-by: YueHaibing Signed-off-by: Herbert Xu

crypto: ux500 - fix incorrect kernel-doc comment syntax

2021-03-26T09:15:58Z

The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are certain files in drivers/crypto/ux500, which follow this syntax, but the content inside does not comply with kernel-doc. Such lines were probably not meant for kernel-doc parsing, but are parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warnings from kernel-doc. E.g., presence of kernel-doc like comment in the header lines for drivers/crypto/ux500/cryp/cryp.h at header causes this warning: "warning: expecting prototype for ST(). Prototype was for _CRYP_H_() instead" Similarly for other files too. Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.

crypto: ux500/hash - Fix worthy kernel-doc headers and remove others

2021-03-26T09:02:35Z

The ones remove here not only fail to conform to kernel-doc, but also provide no value, so let's remove them completely in this case.
