[PATCH 4.9 164/271] mfd: intel-lpss: Release IDA resources

From: Greg Kroah-Hartman
Date: Tue Jan 28 2020 - 09:21:31 EST


From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

[ 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().
