[PATCH] telephony/ixj: use msleep() instead of schedule_timeout()
Replace schedule_timeout() with msleep() to guarantee the task delays as expected. Signed-off-by: Nishanth Aravamudan <nacc@us.ibm.com> Signed-off-by: Domen Puncer <domen@coderock.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
