Subject: tools:iio:iio_generic_buffer: fix trigger-less mode
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f8e81d7e496ea89f377c6935b92022032bed62e5;p=linux-beck.git

tools:iio:iio_generic_buffer: fix trigger-less mode

Passing the trigger-less mode option on the command line causes
iio_generic_buffer to fail searching for an IIO trigger.
Fix this by skipping trigger initialization if trigger-less mode is
requested.

Technically it actually fixes:
7c7e9dad70 where the bug was introduced but as the window to the patch
below that changes the context was very small let's mark it with that.
