[for-next][PATCH 12/13] tracing: Replace kzalloc with kcalloc

[Steven Rostedt <rostedt@goodmis.org>]

From: "Gustavo A. R. Silva" <gustavo@embeddedor.com>

Replace kzalloc() function with its 2-factor argument form, kcalloc().

This patch replaces cases of:

	kzalloc(a * b, gfp)

with:
	kcalloc(a, b, gfp)

This code was detected with the help of Coccinelle.
