2022-08-02dt-bindings: mtd: microchip,mchp48l640: use spi-peripheral-props.yamlKrzysztof Kozlowski
Instead of listing directly properties typical for SPI peripherals, reference the spi-peripheral-props.yaml schema. This allows using all properties typical for SPI-connected devices, even these which device bindings author did not tried yet. Remove the spi-* properties which now come via spi-peripheral-props.yaml schema, except for the cases when device schema adds some constraints like maximum frequency. While changing additionalProperties->unevaluatedProperties, put it in typical place, just before example DTS.

2022-08-02Input: adc-joystick - fix ordering in adc_joystick_probe()Dmitry Torokhov
We should register the IIO buffer before we register the input device, because as soon as the device is registered input handlers may attach to it, resulting in a call to adc_joystick_open() which makes use of the said buffer.

2022-08-02RDMA/rxe: Split qp state for requester and completerBob Pearson
Currently the requester can continue to process send wqes after an local qp operation error is detected because the setting of the qp state to the error state is deferred until later. This patch splits the qp state for the completer and requester into two separate states and sets qp->req.state = QP_STATE_ERROR as soon as the error is detected before another wqe can be executed.

2022-08-02RDMA/rxe: Generate error completion for error requester QP stateLi Zhijian
As per IBTA specification, all subsequent WQEs while QP is in error state should be completed with a flush error. Here we check QP_STATE_ERROR after req_next_wqe() so that rxe_completer() has chance to be called where it will set CQ state to FLUSH ERROR and the completion can associate with its WQE.

2022-08-02RDMA/rxe: Update wqe_index for each wqe error completionLi Zhijian
Previously, if user space keeps sending abnormal wqe, queue.index will keep increasing while qp->req.wqe_index doesn't. Once qp->req.wqe_index==queue.index in next round, req_next_wqe() will treat queue as empty. In such case, no new completion would be generated. Update wqe_index for each wqe completion so that req_next_wqe() can get next wqe properly.
