Subject[PATCH 5.9 060/252] pinctrl: mcp23s08: Print error message when regmap init fails
Date
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.
