[PATCH 5.7 081/244] soundwire: intel: fix memory leak with devm_kasprintf

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>

[ Upstream commit bf6d6e68d2028a2d82f4c106f50ec75cc1e6ef89 ]

The dais are allocated with devm_kcalloc() but their name isn't
resourced managed and never freed. Fix by also using devm_ for the dai
names as well.

Fixes: c46302ec554c5 ('soundwire: intel: Add audio DAI ops')
