Subject: [PATCH 2/6] drm/i915/ddi: convert to struct drm_device log macros.
Date:   Tue, 21 Jan 2020 17:31:51 +0300
Message-Id: <20200121143155.20856-3-wambui.karugax@gmail.com>
In-Reply-To: <20200121143155.20856-1-wambui.karugax@gmail.com>
References: <20200121143155.20856-1-wambui.karugax@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch converts various instances of the printk based logging macros
into the struct drm_device based macros. This was achieved using the
following coccinelle script for matching existing struct
drm_i915_private devices:
@rule1@
identifier fn, T;
@@

fn(...,struct drm_i915_private *T,...) {

-DRM_INFO(
+drm_info(&T->drm,

}

Checkpatch warnings were addressed manually.
