Subject: [PATCH AUTOSEL 5.9 07/21] pinctrl: mcp23s08: Print error message when regmap init fails
Date: Tue, 17 Nov 2020 07:56:38 -0500 [thread overview]
Message-ID: <20201117125652.599614-7-sashal@kernel.org> (raw)
In-Reply-To: <20201117125652.599614-1-sashal@kernel.org>
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
[ Upstream commit a835d3a114ab0dc2f0d8c6963c3f53734b1c5965 ]
It is useful for debugging to have the error message printed
when regmap initialisation fails. Add it to the driver.
