* drm/vc4: Fix resource leak in 'vc4_get_hang_state_ioctl()' in error handling ↵Christophe JAILLET2017-06-12
| | | | | | | | | | | | | | | | | | | | | | path If one 'drm_gem_handle_create()' fails, we leak somes handles and some memory. In order to fix it: - move the 'free(bo_state)' at the end of the function so that it is also called in the eror handling path. This has the side effect to also try to free it if the first 'kcalloc' fails. This is harmless. - add a new label, err_delete_handle, in order to delete already allocated handles in error handling path - remove the now useless 'err' label The way the code is now written will also delete the handles if the 'copy_to_user()' call fails.

* drm: Use new mode_valid() helpers in connector probe helperJose Abreu2017-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the connector probe helper function to use the new encoder->mode_valid(), bridge->mode_valid() and crtc->mode_valid() helper callbacks to validate the modes. The new callbacks are optional so the behaviour remains the same if they are not implemented. If they are, then the code loops through all the connector's encodersXbridgesXcrtcs and calls the callback. If at least a valid encoderXbridgeXcrtc combination is found which accepts the mode then the function returns MODE_OK.
