spi: bcm-qspi: return error if neither hif_mspi nor mspi is available

2023-06-30T13:53:52+00:00

If neither a "hif_mspi" nor "mspi" resource is present, the driver will just early exit in probe but still return success. Apart from not doing anything meaningful, this would then also lead to a null pointer access on removal, as platform_get_drvdata() would return NULL, which it would then try to dereference when trying to unregister the spi master. Fix this by unconditionally calling devm_ioremap_resource(), as it can handle a NULL res and will then return a viable ERR_PTR() if we get one. The "return 0;" was previously a "goto qspi_resource_err;" where then ret was returned, but since ret was still initialized to 0 at this place this was a valid conversion in 63c5395bb7a9 ("spi: bcm-qspi: Fix use-after-free on unbind"). The issue was not introduced by this commit, only made more obvious.

The GPI DMA mode requires for TX DMA to be prepared. Force SPI core to provide TX buffer even if the caller didn't provide one by setting the SPI_CONTROLLER_MUST_TX flag.
