Subject: [PATCH 7/9] KEYS: remove redundant memset

From: Tom Rix <trix@...hat.com>

Reviewing use of memset in keyctrl_pkey.c

keyctl_pkey_params_get prologue code to set params up

	memset(params, 0, sizeof(*params));
	params->encoding = "raw";

keyctl_pkey_query has the same prologue
and calls keyctl_pkey_params_get.

So remove the prologue.
