Could we have the parentheses around numbers removed ? They don't seem to be useful for anything.

Does anything other than these two files (in your second patch):

 drivers/misc/c2c/samsung-c2c.c |  500 ++++++++++++++++++++++++++++++++++++++++
 drivers/misc/c2c/samsung-c2c.h |  300 ++++++++++++++++++++++++

use the regs-c2c.h file? If not, it should be placed next to the drivers itself, and not in some random include directory far away from the drivers.
