OTOH, the current code uses snd_card_free() at\ndisconnection, but this waits for the close of all used fds, hence it\ncan take long. It eventually blocks the upper layer USB ioctls, which\nmay trigger a soft lockup.\n\nAn easy workaround is to replace snd_card_free() with\nsnd_card_free_when_closed(). This variant returns immediately while\nthe release of resources is done asynchronously by the card device\nrelease at the last close.\n\nThe loop of us122l->mmap_count check is dropped as well. The check is\nuseless for the asynchronous operation with *_when_closed()." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
