If Bluetooth SDIO card is unexpectedly removed due to hardware removal
or SDIO issue, it is possible for remove to be called before close.
If an interrupt occurs during this process, it may cause kernel panic.
Therefore, it is necessary to ensure that close is executed before
remove to stop interrupts and cancel txrx workqueue.

Chris Lu (2):
  Bluetooth: btmtksdio: Check function enabled before doing close
  Bluetooth: btmtksdio: Do close if SDIO card removed without close
