2016-01-30intel_scu_ipcutil: underflow in scu_reg_access()Dan Carpenter1-1/+1
"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.

All the production devices use the PC compatible version of this device so don't use the SCU interfaces or the SCU firmware interfaces.

2011-10-24intel_scu_ipcutil: fix major device number handlingKirill A. Shutemov1-2/+6
We need to save major device number to be able to use it for unregister_chrdev() in ipc_module_exit(). ipc_module_init() must return 0 on success, not major device number. Signed-off-by: Kirill A.
