Subject[PATCH 2/2] Documentation: dmaengine: Correctly describe dmatest with channel unset
Date
Currently the documentation states that channels must be configured before
running the dmatest. This has not been true since commit 6b41030fdc79
("dmaengine: dmatest: Restore default for channel"). Fix accordingly.

Allocating Channels
-------------------

-Channels are required to be configured prior to starting the test run.
-Attempting to run the test without configuring the channels will fail.
+Channels do not need to be configured prior to starting a test run. Attempting
+to run the test without configuring the channels will result in testing any
+channels that are available.

Example::

% echo 1 > /sys/module/dmatest/parameters/run
- dmatest: Could not start test, no channels configured
+ dmatest: No channels configured, continue with any

Channels are registered using the "channel" parameter. Channels can be requested by their
name, once requested, the channel is registered and a pending thread is added to the test list.
