Subject: [PATCH 5/5] drm/amd/pm: use bitmap_{from,to}_arr32 where appropriate
Date: Thu, 28 Apr 2022 13:51:16 -0700 [thread overview]
Message-ID: <20220428205116.861003-6-yury.norov@gmail.com> (raw)
In-Reply-To: <20220428205116.861003-1-yury.norov@gmail.com>
The smu_v1X_0_set_allowed_mask() uses bitmap_copy() to convert
bitmap to 32-bit array. This may be wrong due to endiannes issues.
Fix it by switching to bitmap_{from,to}_arr32.
