2023-02-14crypto: aspeed - Fix modular aspeed-acryHerbert Xu1-1/+3
When aspeed-acry is enabled as a module it doesn't get built at all. Fix this by adding it to obj-m. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Reviewed-by: Neal Liu <neal_liu@aspeedtech.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2023-02-10crypto: aspeed - fix type warningsNeal Liu1-4/+4
This patch fixes following warnings: 1. sparse: incorrect type in assignment (different base types) Fix: change to __le32 type. 2. sparse: cast removes address space '__iomem' of expression Fix: use readb to avoid dereferencing the memory.

2023-01-20crypto: aspeed - Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length array declaration in struct aspeed_sham_ctx with flex-array member. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].

devm_ioremap_resource() prints error message in itself. Remove the dev_err call to avoid redundant error message. Signed-off-by: Shang XiaoJing <shangxiaojing@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2022-09-30crypto: aspeed - Fix check for platform_get_irq() errorsYueHaibing1-3/+1
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.
