Analyze and fix the following issue in the Linux kernel code: iio: accel: kx022a fix irq getting
Problem Details: The fwnode_irq_get_byname() was returning 0 at device-tree mapping error. If this occurred, the KX022A driver did abort the probe but errorneously directly returned the return value from fwnode_irq_get_byname() from probe. In case of a device-tree mapping error this indicated success. The fwnode_irq_g...
