The original violation was Samsung's in respect of GPLv2§3.
"Conservancy's GPL Compliance Project for Linux Developers is pleased to announce its role in assisting Samsung in a recent public compliance issue. The compliance issue was brought to Conservancy's attention when source code of an exFAT filesystem driver for Linux was unintentionally released via GitHub, and Conservancy later determined that similar code appeared in binary form only (thus violating GPLv2§3) in a Samsung Linux-based tablet. Samsung has made a source release available on their Open Source Release Center website."
"Conservancy's GPL Compliance Project for Linux Developers worked collaboratively with Ibrahim Haddad, the Group Leader for Open Source at Samsung Research America, and fellow community leaders, throughout the process after this code first appeared on GitHub. Conservancy's primary goal, as always, was to assist and advise toward the best possible resolution to the matter that complied fully with the GPL. Conservancy is delighted that the correct outcome has been reached: a legitimate, full release from Samsung of all relevant source code under the terms of Linux's license, the GPL, version 2."
