Subject: crypto: user - Allow get request with empty driver name
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5d4a5e770d97d87082067886e7097c920b338da5;p=linux-beck.git

crypto: user - Allow get request with empty driver name

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.
