    drm/amdgpu: Update min() to min_t() in 'amdgpu_info_ioctl'
    
    [ Upstream commit a0cc8e1512ad72c9f97cdcb76d42715730adaf62 ]
    
    Fixes the following:
    
    WARNING: min() should probably be min_t(size_t, size, sizeof(ip))
    +               ret = copy_to_user(out, &ip, min((size_t)size, sizeof(ip)));
    
    And other style fixes:
    
    WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
    WARNING: Missing a blank line after declarations
