Subject: [PATCH 04/17] auxdisplay: img-ascii-lcd: Add helper variable dev
Date: Mon, 22 Mar 2021 15:48:35 +0100 [thread overview]
Message-ID: <20210322144848.1065067-5-geert@linux-m68k.org> (raw)
In-Reply-To: <20210322144848.1065067-1-geert@linux-m68k.org>
img_ascii_lcd_probe() has many users of "pdev->dev". Add a shorthand to
simplify the code.
