Subject: [PATCH v2 8/9] sh: pci: Modernize printing of kernel messages
Date:   Wed, 17 Jun 2020 16:36:38 +0200
Message-Id: <20200617143639.18315-9-geert+renesas@glider.be>
In-Reply-To: <20200617143639.18315-1-geert+renesas@glider.be>
References: <20200617143639.18315-1-geert+renesas@glider.be>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

  - Convert from printk() to pr_*(),
  - Add missing continuations,
  - Join broken messages.

Note that printk(KERN_DEBUG ...) is retained, to preserve behavior
(pr_debug() is a dummy if DEBUG is not defined).

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
Tested-by: Guenter Roeck <linux@roeck-us.net>
---
v2:
  - Add Tested-by,
  - Add note about printk(KERN_DEBUG ...).
