Bug: https://bugs.freedesktop.org/show_bug.cgi?id=90626
|
||||||
|
Bug-Debian: https://bugs.debian.org/772716
|
||||||
|
|
||||||
|
Fixes detection of a failed attempt at fetching the entire ROM image
|
||||||
|
in one-shot (a violation of the spec, that works a lot of the time).
|
||||||
|
|
||||||
|
Tested on a HP Zbook 15 G2.
