[PATCH 0/8] clk: check memory returned by {devm_}kasprintf()

From: Claudiu Beznea

While browsing some code I noticed that there are places where pointer
returned by devm_kasprintf() or kasprintf() is not checked. Thus I've
tooked the chance and fixed this (by updating kmerr.cocci script,
changes published at [1]). Along with it some other places where
resources may need to be freed on failure paths were updated.

Thank you,
Claudiu Beznea
