EDAC/device: Fix period calculation in edac_device_reset_delay_period()
Fix period calculation in case user sets a value of 1000. The input of round_jiffies_relative() should be in jiffies and not in milli-seconds. [ bp: Use the same code pattern as in edac_device_workq_setup() for clarity. ] Fixes: c4cf3b454eca ("EDAC: Rework workqueue handling") Signed-off-by: Eliav Farber <farbere@amazon.com> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Cc: <stable@kernel.org> Link: https://lore.kernel.org/r/20221020124458.22153-1-farbere@amazon.com
