staging: dgnc: replace usleep_range with udelay udelay is impelmented using a busy-wait loop and consumes CPU cycles while usleep_range is implemented using interrupts.cls_flush_uart_write() is called after a channel lock is acquired i.e. an atomic context. Hence delay in this method should use udelay instead of usleep_range. Signed-off-by: Aishwarya Pant <aishpant@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
