Subject: scsi: qla2xxx: Use named initializers for q_dev_state
Patch-mainline: v5.18-rc1
Git-commit: 1f652aa0e469ecd870f01f2ab7cf01b4ab71d9b1
References: bsc#1197661
Make q_dev_state a little more readable and maintainable by using named
initializers.
Also convert QLA8XXX_DEV_* macros into an enum and remove
qla83xx_dev_state_to_string(), which is a duplicate of qdev_state().
