Clang static analysis reports this problem
kfd_chardev.c:2594:16: warning: The expression is an uninitialized value.
The computed value will also be garbage
while (ret && i--) {
^~~
i is a loop variable and this block unwinds a problem in the loop.
When the error happens before the loop, this value is garbage.
Move the initialization of i to its decalaration.
Fixes: be072b06c739 ("drm/amdkfd: CRIU export BOs as prime dmabuf objects")
