Title
spi: bcm-qspi: return error if neither hif_mspi nor mspi is available
Summary
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 "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.

Apart from not doing\nanything meaningful, this would then also lead to a null pointer access\non removal, as platform_get_drvdata() would return NULL, which it would\nthen try to dereference when trying to unregister the spi master.\n\nFix this by unconditionally calling devm_ioremap_resource(), as it can\nhandle a NULL res and will then return a viable ERR_PTR() if we get one.\n\nThe \"return 0;\" was previously a \"goto qspi_resource_err;\" where then\nret was returned, but since ret was still initialized to 0 at this place\nthis was a valid conversion in 63c5395bb7a9 (\"spi: bcm-qspi: Fix\nuse-after-free on unbind\").
