ALSA: hda\/tas2781: Cancel async firmware request at unbind<\/p>\n
TAS2781 HDA I2C and SPI queue RCA firmware loading from component
\nbind with request_firmware_nowait(). The firmware loader keeps the
\ncallback module pinned and holds a device reference, but the callback
\nstill uses driver-private HDA state.<\/p>\n
Component unbind removes controls and DSP state immediately. Later
\ndevice removal tears down the TAS2781 private data, including
\ncodec_lock. If the async firmware callback runs after unbind has
\nstarted, it can operate on state that is being torn down.<\/p>\n
Cancel or synchronize the async firmware request before removing
\ncontrols and DSP state. A queued callback is cancelled, and an
\nalready-running callback is allowed to finish before unbind continues.<\/p>\n","protected":false},"excerpt":{"rendered":"
