Subject: Regression with wait_event_timeout in next-20140226

Hi,

while testing next-20140226 I got an issue with the function
wait_event_timeout. When this function timed out instead of returning
0, it returned the value of the timeout passed in parameter. I found
that reverting "sched/wait: Suppress Sparse 'variable shadowing'
warning" fixed this regression.

I got this issue in the driver drivers/i2c/busses/i2c-mv64xxx.c.


Thanks,

Gregory
