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.
