net/nfc/nci/core.c:1455:15: error:
      mixing declarations and code is incompatible with standards before C99
      [-Werror,-Wdeclaration-after-statement]
 1455 |         unsigned int hdr_size = NCI_CTRL_HDR_SIZE;

Maybe enable C99 on older kernel branches ?

The code is

+static bool nci_valid_size(struct sk_buff *skb)
+{
+       BUILD_BUG_ON(NCI_CTRL_HDR_SIZE != NCI_DATA_HDR_SIZE);
+       unsigned int hdr_size = NCI_CTRL_HDR_SIZE;

Swapping those two lines would be another possible fix.
