Subject: [PATCH] bnx2x: use correct format characters
Date: Wed, 16 Mar 2022 14:31:04 -0700 [thread overview]
Message-ID: <20220316213104.2351651-1-morbo@google.com> (raw)
When compiling with -Wformat, clang emits the following warnings:
drivers/net/ethernet/broadcom/bnx2x/bnx2x_link.c:6181:40: warning: format
specifies type 'unsigned short' but the argument has type 'u32'
(aka 'unsigned int') [-Wformat]
ret = scnprintf(str, *len, "%hx.%hx", num >> 16, num);
~~~ ^~~~~~~~~

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.
