6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Cezary Rojewski [ Upstream commit 4dee5c1cc439b0d5ef87f741518268ad6a95b23d ] By sharing 'name' directly, tearing down components may lead to use-after-free errors. Duplicate the name to avoid that. At the same time, update the order of operations - since commit cee28113db17 ("ASoC: dmaengine_pcm: Allow passing component name via config") the framework does not override component->name if set before invoking the initializer.
