[ Upstream commit 7363f2d4c18557c99c536b70489187bb4e05c412 ]
Since commit f63b94be6942 ("i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr") jiffies are stored in i2c_pnx_algo_data.timeout, but wait_timeout and wait_reset are still using it as milliseconds. Convert jiffies back to milliseconds to wait for the expected amount of time.
