If implemented, use panel get_orientation callback rather than calling drm_connector_set_panel_orientation() from within a panel driver that leads to a WARN(). Signed-off-by: Matus Gajdos <[email protected]>

commit c3ed222 upstream. Send along the already-allocated fattr along with nfs4_fs_locations, and drop the memcpy of fattr. We end up growing two more allocations, but this fixes up a crash as: PID: 790 TASK: ffff88811b43c000 CPU: 0 COMMAND: "ls" #0 [ffffc90000857920] panic at ffffffff81b9bfde nxp-imx#1 [ffffc900008579c0] do_trap at ffffffff81023a9b nxp-imx#2 [ffffc90000857a10] do_error_trap at ffffffff81023b78 nxp-imx#3 [ffffc90000857a58] exc_stack_segment at ffffffff81be1f45 nxp-imx#4 [ffffc90000857a80] asm_exc_stack_segment at ffffffff81c009de nxp-imx#5 [ffffc90000857b08] nfs_lookup at ffffffffa0302322 [nfs] nxp-imx#6 [ffffc90000857b70] __lookup_slow at ffffffff813a4a5f nxp-imx#7 [ffffc90000857c60] walk_component at ffffffff813a86c4 nxp-imx#8 [ffffc90000857cb8] path_lookupat at ffffffff813a9553 nxp-imx#9 [ffffc90000857cf0] filename_lookup at ffffffff813ab86b Suggested-by: Trond Myklebust <[email protected]> Fixes: 9558a00 ("NFS: Remove the label from the nfs4_lookup_res struct") Signed-off-by: Benjamin Coddington <[email protected]> Signed-off-by: Anna Schumaker <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

Since 5e41b01a7808 ("drm/panel: Add an API to allow drm to set orientation from panel") it is possible to use panel
get_orientationcallback rather than callingdrm_connector_set_panel_orientation()from within a panel driver that leads to:Some panels drivers have already been updated to implement the callback, so it makes sense to add support for this functionality here, which this patch does.
