Hello All,
The drivers/char/efirtc.c file has ‘struct file_operations.open’ & ‘struct file_operations.close’ functions efi_rtc_open()\ efi_rtc_close() does nothing, just returns ‘0’.
So it accept multiple open files at the same time. If we don’t define these empty function, still driver accepts multiple open() calls at the same time, right?
If so I’d like to know what is the advantage of keeping these function which does nothing instead of removing it from driver?
