Subject: [PATCH v4 04/19] auxdisplay: img-ascii-lcd: Add helper variable dev
Date: Tue, 27 Jul 2021 16:04:44 +0200 [thread overview]
Message-ID: <20210727140459.3767788-5-geert@linux-m68k.org> (raw)
In-Reply-To: <20210727140459.3767788-1-geert@linux-m68k.org>
img_ascii_lcd_probe() has many users of "pdev->dev". Add a shorthand to
simplify the code.
