Patches to make it compatible with kernel 2.3.27 and newer

* Improved monitoring of /proc directories
  Instead of doing:
         proc_bus_i2c->fill_inode = &monitor_bus_i2c;
         void monitor_bus_i2c(struct inode *inode, int fill)
         {
           if (fill)
             MOD_INC_USE_COUNT;
           else
             MOD_DEC_USE_COUNT;
         }
  you can now simply set:
         proc_bus_i2c->owner = THIS_MODULE;
  and this is just as good!
* An old 2.3 problem seemingly never was resolved yet: instead of using
  a *wait_queue directly, you have to use a wait_queue_head_t and
  initialize it properly:
         #if (LINUX_VERSION_CODE < 0x020301)
         static struct wait_queue *pcf_wait = NULL;
         #else
         static wait_queue_head_t pcf_wait;
         #endif

         #if (LINUX_VERSION_CODE >= 0x020301)
            init_waitqueue_head(&pcf_wait);
         #endif
  except for this, semantics remain the same (but using a plain
  wait_queue_head_t instead of a pointer to a wait_queue)
* I had to change the semantics of sensors_register_entry slightly,
  to make the monitoring of /proc/sys/dev/* files possible for kernels
  2.3.27 and newer. It now takes an additional parameter, which you
  can specify as THIS_MODULE.
* THIS_MODULE is only defined in kernels 2.3.13 and later; added
  it to compat.h and the compatibility section of mkpatch.
