If anyone has any objections, please let me know. ------------------ From: Felix Gu [ Upstream commit ef3d549e1deb3466c61f3b01d22fc3fe3e5efb08 ] In f_ospi_probe(), when num_cs validation fails, it returns without calling spi_controller_put() on the SPI controller, which causes a resource leak. Use devm_spi_alloc_host() instead of spi_alloc_host() to ensure the SPI controller is properly freed when probe fails.
