scsi: csiostor: Replace deprecated strncpy() with strscpy() strncpy() is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. 'hw' is kzalloc'd just before this string assignment: | hw = kzalloc(sizeof(struct csio_hw), GFP_KERNEL); ... which means any NUL-padding is redundant. Since CSIO_DRV_VERSION is a small string literal (smaller than sizeof(dest)): ... there is functionally no change in this swap from strncpy() to strscpy(). Nonetheless, let's make the change for robustness' sake -- as it will ensure that drv_version is _always_ NUL-terminated.

scsi: csiostor: Add module softdep on cxgb4 Both cxgb4 and csiostor drivers run on their own independent Physical Function. But when cxgb4 and csiostor are both being loaded in parallel via modprobe, there is a race when firmware upgrade is attempted by both the drivers. When the cxgb4 driver initiates the firmware upgrade, it halts the firmware and the chip until upgrade is complete. When the csiostor driver is coming up in parallel, the firmware mailbox communication fails with timeouts and the csiostor driver probe fails. Add a module soft dependency on cxgb4 driver to ensure loading csiostor triggers cxgb4 to load first when available to avoid the firmware upgrade race.

As a result, the current kernel.org files are a mix of different macro styles. Since this macro/register defines is used by different drivers a few patch series have ended up adding duplicate macro/register define entries with different styles.
