从kernel上游linux-5.10.y分支回合mpt3sas驱动重要的bugfix 相关的commit如下: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=4e1442bae50ed633c2fe8058f47cd79b4ad88b9b 上述commit修复了一个可能导致系统crash的问题，描述如下: During mpt3sas_transport_port_remove(), messages were logged with dev_printk() against &mpt3sas_port->port->dev. At this point the SAS transport device may already be partially unregistered or freed, leading to a crash when accessing its struct device. 修复方案如下: Using ioc_info(), which logs via the PCI device (ioc->pdev->dev), guaranteed to remain valid until driver removal. 该修复比较重要，需要移植到olk-5.10分支.
