I just want to clarify that what I'm suggesting here is something like
this:
/* rx done, wait was interrupted or error occurred */
abort:
dev->interrupt_rx_allowed = true;
- SET_CHECKED(rf69_set_mode(dev->spi, standby));
+ if (rf69_set_mode(dev->spi, standby))
+ pr_err("rf69_set_mode() failed to go standby\n");
wake_up_interruptible(&dev->tx_wait_queue);
if (retval)
return retval;
else
return bytes_total;
I'm pretty sure we want to wake_up() even if it fails. It's not likely
to fail, or if it does then we're probably screwed no matter what. So
this is mostly theoretical.
