[Bug 1945296] Re: To support goodix fp device [27C6:639C]

[Andy Chi]

Hi @sil2100,
For patch goodixmoc-Fix-template-struct-for-required-length-calcula.patch, it's a bug I found when I'm verifying libfprint. Upstream bug here: https://gitlab.freedesktop.org/libfprint/libfprint/-/issues/428. So we include this patch in order to fix some user name length which may too short. Indeed, I'll find more devices to verify this SRU and update the bug description.
