NTB: Use struct_size() helper in devm_kzalloc()

2020-08-24T14:58:06+00:00

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. Also, remove unnecessary variable _struct_size_. This code was detected with the help of Coccinelle and, audited and fixed manually. Addresses-KSPP-ID: https://github.com/KSPP/linux/issues/83 Signed-off-by: Gustavo A. R.

ntb: intel: constify ioreadX() iomem argument (as in generic implementation)

2020-08-15T02:56:57+00:00

The ioreadX() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not. Implementations of ioreadX() do not modify the memory under the address so they can be converted to a "const" version for const-safety and consistency among architectures.
