From ef2a95db89003e8304e429dc48556fecb8c7140b Mon Sep 17 00:00:00 2001 From: Justin Stitt Date: Mon, 11 Jul 2022 17:01:52 -0700 Subject: [PATCH] nfp: fix clang -Wformat warnings When building with Clang we encounter these warnings: | drivers/net/ethernet/netronome/nfp/nfp_app.c:233:99: error: format | specifies type 'unsigned char' but the argument has underlying type | 'unsigned int' [-Werror,-Wformat] nfp_err(pf->cpp, "unknown FW app ID | 0x%02hhx, driver too old or support for FW not built in\n", id); - | drivers/net/ethernet/netronome/nfp/nfp_main.c:396:11: error: format | specifies type 'unsigned char' but the argument has type 'int' | [-Werror,-Wformat] serial, interface >> 8, interface & 0xff); Correct format specifier for `id` is `%x` since the default type for the `nfp_app_id` enum is `unsigned int`. The second warning is also solved by using the `%x` format specifier as the expressions involving `interface` are implicity promoted to integers (%x is used to maintain hexadecimal representation).
