New batch of IrDA patches for 2.4.11-pre3

[Jean Tourrilhes]

	Hi,

	This is the new batch of IrDA patches that have been tested on
the IrDA mailing list in the last 2 weeks. I've just recreated them
for 2.4.11-pre3, so they are ready to go in the kernel..
	Changelog below, patch to follow...

	Jean

[FEATURE] : Add a new feature to the IrDA stack
[CORRECT] : Fix to have the correct/expected behaviour
[CRITICA] : Fix potential kernel crash

          cases without cold reboot
        * resync with v2.4.10 (irlap-hwname e.g.)
        * add MODULE_LICENSE
        * drop MOD_{INC|DEC}_USE_COUNT in favour of SET_MODULE_OWNER
        * rename mtt_bits to qos_mtt_bits parameter like other irda
          drivers use
