Subject: [PATCH] Fix typo in comparision

error: comparison of array 'devnm' equal to a null pointer is always false

User bitwise '&' operator as it is a mask

Fixes
error: use of logical '&&' with constant operand

Remove extraneous parens

error: equality comparison with extraneous parentheses

Remove dead code
