Subject: [BUG] Rockchip SPI: Runtime PM usage count underflow!

Hi,
i am a user of the CONFIG_SPI_SPIDEV device.
It stopped working between 6.8 and 6.10.5.
The SPI bus itself reports no errors to userspace, but no devices
appear connected to the bus.
The platform used is RK3328.
The only spi-related message in dmesg is:
rockchip-spi ff190000.spi: Runtime PM usage count underflow!

Please, can somebody review this issue?

Regards,
  Vicente.
