[Devel] [PATCH rh7 6/6] ms/crypto: user - Allow get request with empty driver name

[Konstantin Khorenko]

From: Herbert Xu <herbert at gondor.apana.org.au>

Currently all get requests with an empty driver name fail with
EINVAL.  Since most users actually want to supply an empty driver
name this patch removes this check.
