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. Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

drawback is a reduced portability and the impossibility to
