Subject: [PATCH v3 1/4] drm/via: drop use of DRM(READ|WRITE) macros
Date: Mon, 22 Jul 2019 22:35:42 +0200 [thread overview]
Message-ID: <20190722203545.8612-2-sam@ravnborg.org> (raw)
In-Reply-To: <20190722203545.8612-1-sam@ravnborg.org>
The DRM_READ, DRM_WRITE macros comes from the deprecated drm_os_linux.h
header file. Remove their use to remove this dependency.
Replace the use of the macros with static inline variants.
v3:
- Use static inline functions, rather than macros (Emil)
- Use dedicated mask variants for byte access (Emil)
