[X/B/F/G/H/Unstable][SRU][PATCH 1/1] Input: i8042 - add ByteSpeed touchpad to noloop table
BugLink: https://bugs.launchpad.net/bugs/1906128
It looks like the C15B laptop got another vendor: ByteSpeed LLC.
Avoid AUX loopback on this touchpad as well, thus input subsystem will be able to recognize a Synaptics touchpad in the AUX port.

Oops, I forgot to add the --suppress-cc flag when sending this out to the Ubuntu kernel mailing list. Sorry for the noise.
