The usage especially in driver code is deprecated and a tree wide effort to clean up and consolidate the (ab)usage of in_interrupt() and related checks is happening. handle_regs_int() is always invoked as part of URB callback which is either invoked from hard or soft interrupt context. Remove the magic assertion. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Thomas Gleixner Cc: Daniel Drake Cc: Ulrich Kunitz Cc: Kalle Valo Cc: "David S.
