Subject: korad-kaxxxxp: remove obsolete code (clear before read, timeout literal)
X-Git-Url: https://sigrok.org/gitweb/?a=commitdiff_plain;h=565c8c354597b1e6013b4eae3ad3f1c9446668e5;p=libsigrok.git

korad-kaxxxxp: remove obsolete code (clear before read, timeout literal)

The korad response read routine clears the receive buffers, so callers
don't have to. This amends commit d2cc60bd4511.

The acquisition timeout is handled by common sw_limits support. Remove
the no longer referenced literal. This amends commit 3f9b48ae5f35.
