error: too few arguments to function 'nrfx_gpiote_init'

Question

Hello, according to the latest nrf5 SDK documentation, the nrfx_gpiote_init function takes no argument, but if I call nrfx_gpiote_init() in a zephyr application, I get the error mentioned above. However, if I call nrfx_gpiote_init(0) instead, the project builds fine, and the pin is functional. Am I missing something here?

nrfx_err_t nrfx_gpiote_init 
 ( 
 void 
 
 )

Function for initializing the GPIOTE module. 
 Only static configuration is supported to prevent the shared resource being customized by the initiator. 
 
 Return values

NRFX_SUCCESS 
 Initialization was successful.

NRFX_ERROR_INVALID_STATE 
 The driver was already initialized.

You should not look at the nRF5 SDK documentation if you're using the NCS. In the nRF5 SDK nrfx_gpiote_init( ) has no arguments, if you're using NCS/Zsephyr, it has one argument which specifies the interrupt priority:

We are aware that there are currently no API reference for the nrfx drivers in the ncs documentation. We are currently working on implementing this. Meanwhile, you have to look at the description above the header file to get information about an nrfx function. E.g. for the nrfx_gpiote_init() function, look at <ncs location>/modules/hal/nordic/nrfx/drivers/include/nrx_gpiote.h . 
 
 I'm not sure what you're trying to do, but you may be able to do it using the API zephyr/include/drivers/gpio.h , which uses the GPIOTE peripheral under the hood. Read more here: https://devzone.nordicsemi.com/f/nordic-q-a/74261/nrf5340-gpioe
