Subject: Mouse no longer working : works in 4.18 : doesn't work in 4.18.5

Mouse worked fine in 4.18 however does not work in 4.18.5 Both kernels
were built with exactly the same .config file (copied from the 4.18
build dir to the un-tar'ed 4.18.5 directory to build)

Any input on root cause and fix / workaround is appreciated.

"Doesn't work" means : syslog and kernel show that:
1. the kernel finds the mouse
2. gpm finds the mouse and detects its protocol
3. mouse cursor does not move and buttons do not work
: not in gpm
: not in X
4. syslog and kernel .config are the same for both versions

Below is the output from syslog and dmesg.

Update : same issue in 4.18.6 @ 20180906
