Subject: ipdbg-la: Fix an issue when capture rate is 100%.
X-Git-Url: http://sigrok.org/gitweb/?a=commitdiff_plain;h=08ecb98e847f929bb0f412f79073f2262045a65b;p=libsigrok.git

ipdbg-la: Fix an issue when capture rate is 100%.

If the capture ratio was set to 100%, the delay counter-value has an
overflow and a delay of 0 samples is used.

This fixes bug #1393.
