From fa1ce54ea38f7f83473fce62e64fefbd7ebd170e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Sun, 5 Jun 2016 11:17:10 +0200 Subject: NFC: fdp: Detect errors from fdp_nci_create_conn() 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 range of data type 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.
