From 664e68bcab5b3e59479494246db980a75822e963 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 12 Oct 2018 12:41:28 +0200 Subject: scsi: ufs: fix integer type usage in uapi header We get a warning from 'make headers_check' about a newly introduced usage of integer types in the scsi/scsi_bsg_ufs.h uapi header: usr/include/scsi/scsi_bsg_ufs.h:18: found __[us]{8,16,32,64} type without #include Aside from the missing linux/types.h inclusion, I also noticed that it uses the wrong types: 'u32' is not available at all in user space, and 'uint32_t' depends on the inclusion of a standard header that we should not include from kernel headers. Change the all to __u32 and similar types here. I also note the usage of '__be32' and '__be16' that seems unfortunate for a user space API. I wonder if it would be better to define the interface in terms of a CPU-endian structure and convert it in kernel space.
