spi: omap2-mcspi: Remove unbalanced pm_runtime_put_sync() calls

2026-08-31T21:54:56+00:00

pm_runtime_put_sync() is called in the probe error path and in remove when nothing holds a runtime PM reference anymore, so it underflows the usage count.

spi: qcom-geni: rename setup_fifo_params() to setup_spi_params() and make it void

2026-08-31T17:51:23+00:00

The function always returned 0 and had no error paths, so change its return type to void. Drop the now-dead ret variable and error check in spi_geni_prepare_message(). setup_fifo_params() is called for both GENI_SE_FIFO and GENI_SE_DMA modes, so the "fifo" in the name is misleading. Rename it to setup_spi_params() to better reflect its purpose of configuring SPI mode parameters (CS, CPHA, CPOL, loopback, LSB-first). No functional change.

spi: sunplus: handle signal interruption in transfer wait

2026-08-31T17:50:16+00:00

wait_for_completion_interruptible_timeout() returns -ERESTARTSYS when interrupted by a signal, 0 on timeout, and positive on success. The previous check was: if (!wait_for_completion_interruptible_timeout(...)) SIGKILL caused the interrupted path to fall through as if the transfer succeeded. The loop then re-entered mutex_lock() on the next iteration, which is TASK_UNINTERRUPTIBLE. The process could not be killed while blocked there. Check ret <= 0 and return -EINTR for the interrupted case so the process can exit promptly on SIGKILL.

spi: sh-msiof: propagate setup runtime-PM errors

2026-08-30T23:37:08+00:00

sh_msiof_spi_setup() ignores pm_runtime_get_sync() before programming native chip-select registers and marking the configuration initialized. Use the checked runtime-PM helper and return failure before register access.

spi: Fix the section ordering in accordance with the comment

2026-08-30T22:53:46+00:00

The comments in all sections tell that the list of the sections should be alphabetically ordered. With time this went apart, mostly for Freescale entries. So, put the things into order again.
