DRM: bug: RADEON_DEBUGFS_MAX_{NUM_FILES => COMPONENTS}
The value of RADEON_DEBUGFS_MAX_NUM_FILES has been used to specify the size of an array, each element of which looks like this: struct radeon_debugfs { struct drm_info_list *files; unsigned num_files; }; Consequently, the number of debugfs files may be much greater than RADEON_DEBUGFS_MAX_NUM_FILES, something that the current code ignores: if ((_radeon_debugfs_count + nfiles) > RADEON_DEBUGFS_MAX_NUM_FILES) { DRM_ERROR("Reached maximum number of debugfs files.\n"); DRM_ERROR("Report so we increase RADEON_DEBUGFS_MAX_NUM_FILES.\n"); return -EINVAL; } This commit fixes this make, and accordingly renames: RADEON_DEBUGFS_MAX_NUM_FILES to: RADEON_DEBUGFS_MAX_COMPONENTS Signed-off-by: Michael Witten <mfwitten@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
