commit e97b81ddbb8b8c72b85330ac4a454a4513dcba8a

[PATCH] i2c-parport: Make type parameter mandatory
This patch forces the user to specify what type of adapter is present when
loading i2c-parport or i2c-parport-light. If none is specified, the driver
init simply fails - instead of assuming adapter type 0.
This alleviates the sometimes lengthy boot time delays which can be caused
by accidentally building one of these into a kernel along with several i2c
slave drivers that have lengthy probe routines (e.g. hwmon drivers).
Kconfig and documentation updated accordingly.
