Before moving greybus core out of staging and moving header files to include/linux some greybus header files were missing the necessary includes. This would trigger compilation faillures with some example errors logged bellow for with CONFIG_KERNEL_HEADER_TEST=y. So, add the necessary headers to compile clean before relocating the header files. ./include/linux/greybus/hd.h:23:50: error: unknown type name 'u16' int (*cport_disable)(struct gb_host_device *hd, u16 cport_id); ^~~ ./include/linux/greybus/greybus_protocols.h:1314:2: error: unknown type name '__u8' __u8 data[0]; ^~~~ ./include/linux/greybus/hd.h:24:52: error: unknown type name 'u16' int (*cport_connected)(struct gb_host_device *hd, u16 cport_id); ^~~ ./include/linux/greybus/hd.h:25:48: error: unknown type name 'u16' int (*cport_flush)(struct gb_host_device *hd, u16 cport_id); ^~~ ./include/linux/greybus/hd.h:26:51: error: unknown type name 'u16' int (*cport_shutdown)(struct gb_host_device *hd, u16 cport_id, ^~~ ./include/linux/greybus/hd.h:27:5: error: unknown type name 'u8' u8 phase, unsigned int timeout); ^~ ./include/linux/greybus/hd.h:28:50: error: unknown type name 'u16' int (*cport_quiesce)(struct gb_host_device *hd, u16 cport_id, ^~~ ./include/linux/greybus/hd.h:29:5: error: unknown type name 'size_t' size_t peer_space, unsigned int timeout); ^~~~~~ ./include/linux/greybus/hd.h:29:5: note: 'size_t' is defined in header '<stddef.h>'; did you forget to '#include <stddef.h>'? ./include/linux/greybus/hd.h:1:1: +#include <stddef.h> /* SPDX-License-Identifier: GPL-2.0 */ ./include/linux/greybus/hd.h:29:5: size_t peer_space, unsigned int timeout); ^~~~~~ ./include/linux/greybus/hd.h:30:48: error: unknown type name 'u16' int (*cport_clear)(struct gb_host_device *hd, u16 cport_id); ^~~ ./include/linux/greybus/hd.h:32:49: error: unknown type name 'u16' int (*message_send)(struct gb_host_device *hd, u16 dest_cport_id, ^~~ ./include/linux/greybus/hd.h:33:32: error: unknown type name 'gfp_t' struct gb_message *message, gfp_t gfp_mask); ^~~~~ ./include/linux/greybus/hd.h:35:55: error: unknown type name 'u16' int (*latency_tag_enable)(struct gb_host_device *hd, u16 cport_id); Reported-by: kbuild test robot <lkp@intel.com> Reported-by: Gao Xiang <hsiangkao@aol.com> Signed-off-by: Rui Miguel Silva <rmfrfs@gmail.com> Signed-off-by: Rui Miguel Silva <rui.silva@linaro.org> Link: https://lore.kernel.org/r/20190827155302.25704-1-rui.silva@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
