Subject: asix-sigma: nits in the list of firmware files
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=742368a2bc2e4a01b0fbcdc6d5aa2bb4c0bcda4c;p=libsigrok.git

asix-sigma: nits in the list of firmware files

Eliminate an unnecessary magic number for the maximum filename length of
SIGMA netlists. Use a more compact source code phrase to "unclutter" the
list of filenames and their features/purpose. Move the filesize limit to
the list of files to simplify future maintenance.
