Subject: Various fixes/updates to make the driver compile.
X-Git-Tag: libsigrok-0.4.0~602
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=6fcf3f0a22e3dd2467fd09b0cad92b36e0409fc4;p=libsigrok.git

Various fixes/updates to make the driver compile.

This patchset was originally done by eightdot <redacted> by
manually forward-porting parts of the changes done by Bert Vermeulen (see
previous commits), but then heavily modified by Uwe Hermann to be based on
top off the (git-)rebased patches from Bert Vermeulen instead.

Note: This initial DSLogic code is *not* yet in a working or usable
state. It should be considered as a basis for further work only, for now.
