Date: Tue, 28 Sep 2021 03:19:30 -0700 From: Prashant Malani <pmalani@...omium.org> To: linux-kernel@...r.kernel.org Cc: bleung@...omium.org, Prashant Malani <pmalani@...omium.org>, Andy Shevchenko <andriy.shevchenko@...ux.intel.com>, Hans de Goede <hdegoede@...hat.com>, Mark Gross <mgross@...ux.intel.com>, Mika Westerberg <mika.westerberg@...ux.intel.com>, platform-driver-x86@...r.kernel.org (open list:X86 PLATFORM DRIVERS) Subject: [PATCH 1/3] platform/x86: intel_scu_ipc: Fix busy loop expiry time The macro IPC_TIMEOUT is already in jiffies (it is also used like that elsewhere in the file when calling wait_for_completion_timeout()). Don’t convert it using helper functions for the purposes of calculating the busy loop expiry time.
