Description

Keywords: gpio_v2_00_a driver, gpio, gpio_v2_00_a, Processor IP,

The software code in the gpio_v2_00_a driver includes:
Register = XIIF_V123B_READ_IIER(InstancePtr->BaseAddress +
XGPIO_IPIF_OFFSET);
XIIF_V123B_WRITE_IIER(InstancePtr->BaseAddress + XGPIO_IPIF_OFFSET,
Mask & ~Register);

This should be changed to:
~Mask & Register
