|
|
|
|
Fix below issue reported by Coverity, actually, don't need this
|
|
condition check here, remove it.

CID undefined (#1 of 1): Wrong operator used (CONSTANT_EXPRESSION_RESULT)operator_confusion:
|
|
(16UL /* 1UL << 4 */) | (__u16)(__le16)tcd->csr is always 1/true regardless of the values of its operand.
|
|
This occurs as the logical first operand of "&&".
