`comedi_event()` is called from low-level drivers to handle comedi asynchronous command event flags. Some events cause waiting tasks to be woken up, and a `SIGIO` signal to be sent via `kill_fasync()`. The signal code is `POLL_OUT` if the subdevice supports commands in the "write" direction, or `POLL_IN` for the "read" direction. If the subdevice supports commands in either direction, it sends two `SIGIO` signals, one with each code. Change that latter case to only send one `SIGIO` signal, using the direction of the current command to determine the signal code. If the `CMDF_WRITE` flag is set in the current command, it's in the "write" direction, otherwise it's in the "read" direction. Signed-off-by:

`comedi_event()` is called from low-level drivers to handle asynchronous command event flags that are stored in `s->async->events` for subdevice `s`. It normally clears the event flags as well. As a safety check, it does nothing if no asynchronous command is running, but it leaves `s->async->events` unchanged in this case. For additional safety, change it to always clear the event flags to avoid leaving stale event flags set when another asynchronous command is set up. Signed-off-by:

`comedi_is_subdevice_in_error()` is only used by `comedi_read()` and `comedi_write()` and is only called (soon) after `comedi_is_subdevice_running()` returns `false` (with extra conditions in the case of `comedi_write()`). `comedi_is_subdevice_running()` and `comedi_get_subdevice_runflags()` both call `comedi_get_subdevice_runflags()` which uses the subdevice's spin-lock. Eliminate one use of the subdevice's spin-lock in `comedi_read()` and `comedi_write()` by calling `comedi_get_subdevice_runflags()` and checking the runflags directly. Add a couple of inline functions to check the runflags: `comedi_is_runflags_running()` and `comedi_is_runflags_in_error()`. These do the same test on runflags as `comedi_is_subdevice_running()` and `comedi_is_subdevice_in_error()` but get passed the runflags value directly. `comedi_is_subdevice_in_error()` is no longer used, so remove it.

`comedi_set_subdevice_runflags()` changes the comedi subdevice's `runflags` member according to a bit-mask and new bit values. It's name might suggest that it only "sets", not "clears". Rename it to `comedi_update_subdevice_runflags()` to avoid confusion. Signed-off-by:

Static inline functions are preferred over macros. The inline function obd_check_dev_active is introduced to replace OBD_CHECK_DEV_ACTIVE. All functions that call obd_check_dev_active store the return values and return them if they represent an error code. Some of the changes were carried out manually while others were done using coccinelle. Signed-off-by:
