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