usb: ums: fix disk capacity miscalculation and code cleanup
This patch prevents: - ums disk capacity miscalculation because of integer overflow Changes v2: - Prevents passing zero size disk capacity to ums gadget driver - Change function ums_get_capacity() to ums_disk_init() and do ums disk initialization before gadget init - Remove unnecessary code from mass storage driver Signed-off-by: Przemyslaw Marczak <> Cc: Marek Vasut <>
