When SYSTEM_TRUSTED_KEYRING=n my build fails like this:

kernel/module_signing.c: In function 'request_asymmetric_key':
kernel/module_signing.c:161:36: error: 'system_trusted_keyring' undeclared (first use in this function)
kernel/module_signing.c:161:36: note: each undeclared identifier is reported only once for each function it appears in

Fix this by replacing "select" with "depends on" KEYS Kconfig.

For more details follow the thread in [1].

Tested against Linux-Next (next-20130118).
