[PATCH] arm64: defconfig: Enable USB_UAS in arm64 configuration

[Akash Kumar]

The USB Attached SCSI (UAS) protocol is supported by many modern USB
storage devices. It provides significantly higher performance than the
legacy Mass Storage Class (MSC) by supporting multiple outstanding
commands and command queuing.

Enable CONFIG_USB_UAS=y in the default arm64 configuration to provide
better out-of-the-box performance for USB storage devices on arm64
platforms.

[Severity: Low]
This isn't a bug, but there is a mismatch between the Author email and the
Signed-off-by email. 

The Author is listed as akash.kumar@oss.qualcomm.com, but the Signed-off-by
tag uses akakum@qti.qualcomm.com. 

Should these match to satisfy the standard Developer Certificate of Origin
expectations for patch submission?

This is a bug... DCO email must match.

Anyone in upstream actually uses it for development? Care to show some
examples?

This is not a distro config, you know...

For sure not built-in...
