Subject: [PATCH V2] staging: gpib: Remove unused value
The variable `complement_count` is assigned a value which is again
overwritten in the next statement.
Fix this by removing the first value assigning statement
This issue was reported by Coverity Scan.
Report:
CID 1600790: (#1 of 1): Unused value (UNUSED_VALUE)
assigned_value: Assigning value from length to complement_count here,
but that stored value is overwritten before it can be used.
