Subject: i40e: Initialize pointer in client_release function
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=682d11d7001e61710b282df51a51250a57514772;p=openwrt%2Fstaging%2Fblogic.git

i40e: Initialize pointer in client_release function

The function i40e_client_release has a print statement that uses an
adapter pointer which is not initialized if a previous if statement
is not true. Hence, intialize it in the right place.
