`ni_ai_poll()` currently acquires (and later releases) the comedi device's spin-lock iff `in_interrupt()` returns 0. However, it is only called during processing of a `COMEDI_POLL` ioctl so `in_interrupt()` will always return 0 in this case. Remove this test and acquire/release the spin-lock unconditionally. This eliminates a sparse warning about different lock contexts for basic block. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
