Subject: usb_power_delivery: Use "if not self.samplerate" form.
X-Git-Tag: libsigrokdecode-0.4.0~15
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=033e7d4db76f2e2a289d5567e9532f26201cfa74;p=libsigrokdecode.git

usb_power_delivery: Use "if not self.samplerate" form.

Use the "if not self.samplerate" form, which catches both the case
where self.samplerate is None, as well as the case where it is 0.

This is also consistent with all the other PDs.
