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

In the Linux kernel, the following vulnerability has been resolved:

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

If neither a "hifmspi" 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 platformget_drvdata() would return NULL, which it would then try to dereference when trying to unregister the spi master.

Fix this by unconditionally calling devmioremapresource(), 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 qspiresourceerr;" 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.
