Subject: [PATCH 2/3] drm/amd/pm/powerplay/hwmgr: use bitwise or for bitmasks addition
Date: Sun, 15 Jan 2023 12:47:11 +0530 [thread overview]
Message-ID: <77f7e23c8a40cbaa72aa92b35e013f43f0952f45.1673766696.git.drv@mailo.com> (raw)
In-Reply-To: <cover.1673766696.git.drv@mailo.com>
For bit mask addition, it is recommended to use or operator "|" instead
of numerical addition as the former is quicker and cleaner. Change
suggested by orplus.cocci Coccinelle semantic patch.
