If anyone has any objections, please let me know. ------------------ From: Zilin Guan [ Upstream commit 6cbba46934aefdfb5d171e0a95aec06c24f7ca30 ] In setup_nic_devices(), the initialization loop jumps to the label setup_nic_dev_free on failure. The current cleanup loop while(i--) skip the failing index i, causing a memory leak. Fix this by changing the loop to iterate from the current index i down to 0. Compile tested only. Issue found using code review.
