Merge tag 'bootconfig-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull bootconfig updates from Masami Hiramatsu:
 "Minor fixes for handling errors:
   - fix off-by-one in xbc_verify_tree() next node check
   - increment xbc_node_num after node init succeeds
   - validate child node index in xbc_verify_tree()

  Code cleanups (mainly type/attribute changes):
   - clean up comment typos and bracing
   - drop redundant memset of xbc_nodes
   - replace linux/kernel.h with specific includes
   - narrow flag parameter type from uint32_t to uint16_t
   - constify xbc_calc_checksum() data parameter
   - fix signed comparison in xbc_node_get_data()
   - use size_t for strlen result in xbc_node_match_prefix()
   - use signed type for offset in xbc_init_node()
   - use size_t for key length tracking in xbc_verify_tree()
   - change xbc_node_index() return type to uint16_t"
