*** Primary Check 2: Check that /dev/i2c-* exist and writable ***
Current user: root (0)
Checking /dev/i2c-* devices...
Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).
Typically, this access is enabled by:
- setting the group for /dev/i2c-* to i2c
- setting group RW permissions for /dev/i2c-*
- making the current user a member of group i2c
Alternatively, this can be enabled by just giving everyone RW permission
The following tests probe for these conditions.
