Log:
gpio-s3c6410.c (set_h): correct offset of pull-up register (by Andy Pevy)

Andy wrote:

  In the set_h function, the offset used for calculating the pud
  register address is set to 8 but the actual offset for the 3 registers
  that use the function (GPIO ports H, K and L) should be 0x0C.

  I have changed my code and I can now successfully use port K
  on my application.
