Subject: spi: Create the out_bitrate annotation unconditionally
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=f04db50ab7bbc59b7668396500b92ae2d3418f0e;p=libsigrokdecode.git

spi: Create the out_bitrate annotation unconditionally

The start() method is called before the metadata() method, which results in the
the out_bitrate instance variable never getting created and ending up as an
AttributeError when decoding.

(observed with sigrok-cli and VCD file as the input)
