Dan Carpenter 45c4556d2b intel_scu_ipcutil: underflow in scu_reg_access() 
commit b1d353ad3d upstream.

"count" is controlled by the user and it can be negative.  Let's prevent
that by making it unsigned.  You have to have CAP_SYS_RAWIO to call this
function so the bug is not as serious as it could be.

Fixes: 5369c02d95 ('intel_scu_ipc: Utility driver for intel scu ipc')
