    Input: HIL - various fixes for HIL drivers
    
     - mark some structures const or __read_mostly
     - hilkbd.c: fix uninitialized spinlock in HIL keyboard driver
     - hil_mlc.c: use USEC_PER_SEC instead of 1000000
     - hp_sdc: bugfix for request_irq()/free_irq() parameters, this prevented
               multiple load/unload cycles as module
