[Kernel-janitors] [PATCH 2.6.9-rc2 14/16] isdn/isdn_tty: replace

[Nishanth Aravamudan <nacc@us.ibm.com>]

Any comments would be appreciated. This is a re-push of a patch
submitted a few months ago which has not been merged as of
2.6.9-rc1-mm5 / 2.6.9-rc2. Also, there will be one more patch than I
expected (hence the total just went up by one in this series).

Description: Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected.
