When compiling with -Wformat, clang emits the following warnings:
fs/nfsd/flexfilelayout.c:120:27: warning: format specifies type 'unsigned
char' but the argument has type 'int' [-Wformat]
"%s.%hhu.%hhu", addr, port >> 8, port & 0xff);
~~~~ ^~~~~~~~~
%d
fs/nfsd/flexfilelayout.c:120:38: warning: format specifies type 'unsigned
char' but the argument has type 'int' [-Wformat]
"%s.%hhu.%hhu", addr, port >> 8, port & 0xff);
~~~~ ^~~~~~~~~~~
%d
The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.
