Subject: [PATCH] scsi: scsi_debug: Re-arrange parameters alphabetically
References: jsc#SLE-15442 bsc#1180814 ltc#187461
Patch-mainline: v5.8-rc1
Git-commit: 5d80707673581f95506cb2457354705ea4b51c46
This module has a lot of parameters and when searching for one, the author
prefers them in alphabetical order. This can lead to somewhat illogical
ordering (e.g. inq_product before inq_vendor). However it is not clear what
another sensible total logical ordering would be.
