I work at https://t2linux.org/, a project aimed to bring Linux to T2 Macs.

Kerem helped in developing the driver for the Touch Bar on these Macs.
During development, he did some improvements to the HID core, USB core
and DRM, which are not specific to the Macs, but are used in the driver.

As to why he didn't submit himself, unfortunately Kerem seems to have left
the project and is not contactable at all. Fortunately, the patches he contributed
were signed off by him. Since we have his Signed-off-by and the code is GPL2,
IMO, I can legally submit this.
