Subject: [PATCH AUTOSEL 4.14 243/371] mfd: intel-lpss: Release IDA resources
From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
[ Upstream commit 02f36911c1b41fcd8779fa0c135aab0554333fa5 ]
ida instances allocate some internal memory for ->free_bitmap
in addition to the base 'struct ida'. Use ida_destroy() to release
that memory at module_exit().
Fixes: 4b45efe85263 ("mfd: Add support for Intel Sunrisepoint LPSS devices")
