driver core: platform: fix u32 greater or equal to zero comparison
[ Upstream commit 0707cfa5c3ef58effb143db9db6d6e20503f9dec ]
Currently the check that a u32 variable i is >= 0 is always true because
the unsigned variable will never be negative, causing the loop to run
forever. Fix this by changing the pre-decrement check to a zero check on
i followed by a decrement of i.
Addresses-Coverity: ("Unsigned compared against 0")
Fixes: 39cc539f90d0 ("driver core: platform: Prevent resouce overflow from causing infinite loops")
