pinctrl: max77620: Use common error handling code in max77620_pinconf_set()
* Add a jump target so that a specific error message is stored only once at the end of this function implementation. * Replace two calls of the function "dev_err" by goto statements. * Adjust two condition checks. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
