NTB: perf: Fix an error code in perf_setup_inbuf()

2021-09-22T10:39:27Z

[ Upstream commit 0097ae5f7af5684f961a5f803ff7ad3e6f933668 ] When the function IS_ALIGNED() returns false, the value of ret is 0. So, we set ret to -EINVAL to indicate this error. Clean up smatch warning: drivers/ntb/test/ntb_perf.c:602 perf_setup_inbuf() warn: missing error code 'ret'.

NTB: Add support for EPF PCI Non-Transparent Bridge

2021-02-23T20:12:53Z

Add support for EPF PCI Non-Transparent Bridge (NTB) devices. This driver is platform independent and may be used by any platform that has multiple PCI endpoint instances configured using the pci-epf-ntb driver. The driver connnects to the standard NTB subsystem interface. The EPF NTB device has a configurable number of memory windows (max 4), a configurable number of doorbells (max 32), and a configurable number of scratch-pad registers.

NTB: Use struct_size() helper in devm_kzalloc()

2020-08-24T14:58:06Z

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.
