Subject: hp-3478a: use symbolic name for status register bit field
X-Git-Url: http://sigrok.org/gitweb/?a=commitdiff_plain;h=d07ef6f786e423df25e1d7155df988fba9fb8669;p=libsigrok.git

hp-3478a: use symbolic name for status register bit field

The hp_3478a_receive_data() routine uses SPOLL to only communicate
measurement data when they have become available. Use a symbolic name
for the tested bitfield for consistency with other driver locations
and for improved readability.
