[PATCH v11 5/5] can: m_can: Fix checkpatch issues on existing code

From: Dan Murphy
Date: Tue Mar 19 2019 - 13:28:00 EST


Fix checkpatch issues found during the m_can framework creation.
The code the issues were in, was in untouched code and these
changes should be done separately as to not be confused with the
framework changes.

Fix these 3 check issues:
CHECK: Unnecessary parentheses around 'cdev->can.state != CAN_STATE_ERROR_WARNING'
if (psr & PSR_EW &&
(cdev->can.state != CAN_STATE_ERROR_WARNING)) {

CHECK: Unnecessary parentheses around 'cdev->can.state != CAN_STATE_ERROR_PASSIVE'
if ((psr & PSR_EP) &&
(cdev->can.state != CAN_STATE_ERROR_PASSIVE)) {

CHECK: Unnecessary parentheses around 'cdev->can.state != CAN_STATE_BUS_OFF'
if ((psr & PSR_BO) &&
(cdev->can.state != CAN_STATE_BUS_OFF)) {
