Subject: [PATCH 4/4] drm/amd/pm: use bitmap_{from,to}_arr32 where appropriate
Date: Wed, 20 Apr 2022 15:41:28 -0700 [thread overview]
Message-ID: <20220420224128.911759-1-yury.norov@gmail.com> (raw)
In-Reply-To: <20220420222530.910125-1-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 endianness issues.
Fix it by switching to bitmap_{from,to}_arr32.
