Subject: [PATCH] staging: wilc1000: Removed unused variables
Message-ID: <20160228115106.GA16477@Karyakshetra>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

User-Agent: Mutt/1.5.23 (2014-03-12)

Variables pcgroup_encrypt_val,pccipher_group,pcwpa_version,
hold different values at different stages of the execution of
connect(), however they are not being used anywhere.
Hence, the unused variables have been removed.

This was done using Coccinelle.
