drivers/nfc/fdp/fdp.c: In function ‘fdp_nci_patch_otp’:
drivers/nfc/fdp/fdp.c:373: warning: comparison is always false due to limited
range of data type
drivers/nfc/fdp/fdp.c: In function ‘fdp_nci_patch_ram’:
drivers/nfc/fdp/fdp.c:444: warning: comparison is always false due to limited

fdp_nci_create_conn() may return a negative error code, which is
silently ignored by assigning it to a u8.
Change conn_id from u8 to int to fix this.

fdp_nci_patch_otp() and fdp_nci_patch_ram() are almost identical.
Please merge them, or create a common helper.
v2:
- Rebased, updated, reworded.
