Change the prototype of matrix_output_unselect_delay() (#13045)
The prototype of matrix_output_unselect_delay() has been changed as follows. ```c void matrix_output_unselect_delay(uint8_t line, bool key_pressed); ``` Currently, no keyboard seems to be redefining `matrix_output_unselect_delay()`, so there is no change in the system behavior. With this change, the keyboard level code can get some optimization hints, for example, the following. ```c void matrix_output_unselect_delay(uint8_t line, bool key_pressed) { /* If none of the keys are pressed, * there is no need to wait for time for the next line. */ if (key_pressed) { #ifdef MATRIX_IO_DELAY # if MATRIX_IO_DELAY > 0 wait_us(MATRIX_IO_DELAY); # endif #else wait_us(30); #endif } } ```
