Right, I've added an explanation in the changelog text now:

 The s3c_gpio_cfgall_range() function is an internal interface of the
 samsung gpio driver and should not be called directly by drivers, so
 move the iis pin initialization into the boards.

+This means the pin configuration is only run once at early boot, rather
+than each time the driver binds, but the effect should be the same.
