sctp: chunk.c: correct format string for size_t in printk
According to Documentation/core-api/printk-formats.rst, size_t should be
printed with %zu, rather than %Zu.
In addition, using %Zu triggers a warning on clang (-Wformat-extra-args):
net/sctp/chunk.c:196:25: warning: data argument not used by format string [-Wformat-extra-args]
__func__, asoc, max_data);
~~~~~~~~~~~~~~~~^~~~~~~~~
./include/linux/printk.h:440:49: note: expanded from macro 'pr_warn_ratelimited'
printk_ratelimited(KERN_WARNING pr_fmt(fmt), ##__VA_ARGS__)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
./include/linux/printk.h:424:17: note: expanded from macro 'printk_ratelimited'
printk(fmt, ##__VA_ARGS__); \
~~~ ^
