+Subject: gpio: tc35894: fix up tc35894 interrupt configuration
+
+From: dillon min <dillon.minfei@gmail.com>
+
+commit 214b0e1ad01abf4c1f6d8d28fa096bf167e47cef upstream.
+
+The offset of regmap is incorrect, j * 8 is move to the
+wrong register.
+
+for example:
+
+asume i = 0, j = 1. we want to set KPY5 as interrupt
+falling edge mode, regmap[0][1] should be TC3589x_GPIOIBE1 0xcd
+but, regmap[i] + j * 8 = TC3589x_GPIOIBE0 + 8 ,point to 0xd4,
+this is TC3589x_GPIOIE2 not TC3589x_GPIOIBE1.
+
+Fixes: d88b25be3584 ("gpio: Add TC35892 GPIO driver")
