/* The btmrvl_sdio_remove() callback function is called
* when user removes this module from kernel space or ejects
* the card from the slot. The driver handles these 2 cases
* differently.
* If the user is removing the module, a MODULE_SHUTDOWN_REQ
* command is sent to firmware and interrupt will be disabled.
* If the card is removed, there is no need to send command
* or disable interrupt.
*
* The variable 'user_rmmod' is used to distinguish these two
* scenarios. This flag is initialized as FALSE in case the card
* is removed, and will be set to TRUE for module removal when
* module_exit function is called.
