[PATCH] clk: at91: Use kcalloc() in of_at91_clk_pll_get_characteristics()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 19 Apr 2017 19:43:03 +0200

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.
