The size for jack_switch_types array is currently controlled by a MACRO 'SND_JACK_SWITCH_TYPES', whose value needs to be updated everytime a new jack switch type is added. Remove this MACRO and use ARRAY_SIZE instead to get size of the array.

The changes in ALSA side (this one and patch 3) look good.
Rather a bigger question is about the addition of the new input bit. This needs the review and ack from input subsystem people.
Adding to Cc.
thanks,
