Subject: ASIX Sigma: Fix firmware loading bug.
X-Git-Tag: libsigrok-0.1.0~305
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=82957b65b111437ebe445b7f165719eec2d4e147;p=libsigrok.git

ASIX Sigma: Fix firmware loading bug.

When no firmware file is found, return the right error code so sigrok
doesn't continue running with no firmware loaded.

Thanks Martin Stensgård <redacted> for the patch!
