Does anyone know why 64bit kernels do not call release_region in i8042_platform_exit? Why is it allowed on 32bit kernels? drivers/input/serio/i8042-io.h 83 static inline void i8042_platform_exit(void) 84 { 85 #if !defined(__sh__) && !defined(__alpha__) && !defined(CONFIG_PPC64) 86 release_region(I8042_DATA_REG, 16); 87 #endif 88 }
