[PATCH v2] mt76: fix some checkpatch warnings

Ryder Lee ryder.lee at mediatek.com
Tue Aug 20 20:11:15 PDT 2019


This fixes the following checkpatch warnings:
CHECK: Alignment should match open parenthesis
CHECK: No space is necessary after a cast

Signed-off-by: Ryder Lee <ryder.lee at mediatek.com>
---
Changes since v2: remove false positive checkpatch warnings.
Changes since v1: none.
