Code cleanup and coding style compliance changes:
- Extraneous spaces within parentheses, brackets and braces removed.
- Unnecessary initializations removed.
- All lines shorter than 80 columns.
- Constant msgs size of 2 replaced with ARRAY_SIZE(msgs).
- Single statement braces banished.
- udelay() -> msleep().
- Unused ks0127_getcrop() removed.
- schedule_timeout() -> schedule_timeout_interruptible().
- current->state = TASK_INTERRUPTIBLE removed.
- module_init/module_exit corrected.
- Removed the Emacs stuff.
