Subject: Introduce standard implementation of the dev_list() callback
X-Git-Tag: libsigrok-0.5.0~464
X-Git-Url: http://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=c01bf34ca264b268fee2e71ab918c71d28dc3018

Introduce standard implementation of the dev_list() callback

Every single hardware driver has the very same implementation of the
dev_list() callback. Put this into a helper function in the standard helper
library and use it throughout the drivers. This reduces boiler-plate code
by quite a bit.
