Commit 5a6ea70 ("samples/bpf: Remove unnecessary -I flags from libbpf EXTRA_CFLAGS") fixed the build error caused by redundant include path for samples/bpf, but not samples/hid. Apply the same fix on samples/hid as well. Fixes: 13b2548 ("kbuild: change working directory to external module directory with M=") Tested-by: Ruowen Qin <[email protected]> Signed-off-by: Jinghao Jia <[email protected]>
Commit 13b2548 ("kbuild: change working directory to external module directory with M=") changed kbuild working directory of bpf and hid samples to samples/{bpf,hid}, which broke the vmlinux path for VMLINUX_BTF, as the Makefiles assume the current work directory to be the kernel output directory and use a relative path (i.e., ./vmlinux): Makefile:316: *** Cannot find a vmlinux for VMLINUX_BTF at any of " /path/to/linux/samples/bpf/vmlinux", build the kernel or set VMLINUX_BTF like "VMLINUX_BTF=/sys/kernel/btf/vmlinux" or VMLINUX_H variable. Stop. Correctly refer to the kernel output directory using $(objtree).
