Subject: [PATCH 2/3] libbpf: Fixed various checkpatch issues in libbpf.c
Fixed following checkpatch issues:
WARNING: Block comments use a trailing */ on a separate line
+ * other BPF program's BTF object */
WARNING: Possible repeated word: 'be'
+ * name. This is important to be be able to find corresponding BTF
ERROR: switch and case should be at the same indent
+ switch (ext->kcfg.sz) {
+ case 1: *(__u8 *)ext_val = value; break;
+ case 2: *(__u16 *)ext_val = value; break;
+ case 4: *(__u32 *)ext_val = value; break;
+ case 8: *(__u64 *)ext_val = value; break;
