From: Ranjani Sridharan Date: Wed, 18 Jan 2023 10:12:54 +0000 (+0200) Subject: ASoC: SOF: sof-audio: skip prepare/unprepare if swidget is NULL X-Git-Tag: baikal/aarch64/sdk6.1~82 X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=50a75282974e2df3530b73c56252a732f5ccf915;p=kernel.git ASoC: SOF: sof-audio: skip prepare/unprepare if swidget is NULL commit 0ad84b11f2f8dd19d62d0b2ffd95ece897e6c3dc upstream. Skip preparing/unpreparing widgets if the swidget pointer is NULL. This will be true in the case of virtual widgets in topology that were added for reusing the legacy HDA machine driver with SOF.
