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__); \ ~~~ ^ Fixes: 5b5e0928 ("lib/vsprintf.c: remove %Z support") Link: https://github.com/ClangBuiltLinux/linux/issues/378Signed-off-by: Matthias Maennich <maennich@google.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.
