Subject: drivers: rename and reorganize config get/set
X-Git-Tag: dsupstream~322
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=035a1078fda93cf1da37d19b3a1d95311b99b00f;p=libsigrok.git

drivers: rename and reorganize config get/set

The driver API calls info_get() and dev_config_set() have been renamed
to config_get() and config_set(), respectively.
