Subject: resource: Improve logging output.
X-Git-Tag: libsigrok-0.5.0~216
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=7ade12b470366a03f7bf84e4989c9d3593dc333b;p=libsigrok.git

resource: Improve logging output.

Don't show duplicate lines (per default) such as

  sr: resource: Failed to locate 'saleae-logic16-fx2.fw'.
  sr: resource: Failed to open resource 'saleae-logic16-fx2.fw'.

The first one is now an sr_dbg() instead of sr_err().

Also, mention that a higher loglevel will give more information as to
where the backend is looking for resources / firmware files.

This fixes bug #806.
