Subject: [PATCH v2 21/24] pinctrl: lynxpoint: Implement ->pin_dbg_show()
Date: Mon, 9 Dec 2019 15:09:23 +0200 [thread overview]
Message-ID: <20191209130926.86483-22-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20191209130926.86483-1-andriy.shevchenko@linux.intel.com>
The introduced callback ->pin_dbg_show() is useful for debugging.
