Subject: [PATCH v3 1/9] powerpc/ima: Drop unnecessary check for
 CONFIG_MODULE_SIG

When CONFIG_MODULE_SIG is disabled set_module_sig_enforced() is defined
as an empty stub, so the check is unnecessary.
The specific configuration option for set_module_sig_enforced() is
about to change and removing the check avoids some later churn.

Signed-off-by: Thomas Weißschuh <linux@...ssschuh.net>

---
This patch is not strictly necessary right now, but makes looking for
usages of CONFIG_MODULE_SIG easier.
