The function devm_kzalloc has a first argument of type struct device *.
This is the type of argument required by printing functions such as
dev_dbg, dev_err, etc. Thus, functions like pr_err should not normally
be used after a call to devm_kzalloc. Thus, all pr_err occurances are
replaced with dev_err function calls.

This was done using Coccinelle, the patch being:

@@
expression E1,E2;
expression list args;
identifier I;
@@

E1 = (struct I *)devm_kzalloc(E2, ...);
<...
- pr_err(
+ dev_err(E2,
 args);
...>

Changes from version1:
	* Removed ++dev_err and replaced it with +dev_err in the
 semantic patch as ++ is not necessary.
