Subject: [PATCH] Fix two Acer FA100 SSDs from interfering in one PC

In order for two Acer FA100 SSDs to work in one PC (in the case of myself,
a Lenovo Legion T5 28IMB05), and not show one drive and not the other,
and sometimes mix up what drive shows up (randomly), these two lines of
code need to be added, and then both of the SSDs will show up and not
conflict when booting off of one of them. If you boot up your computer with
both SSDs installed without this patch, you may also randomly get into a
kernel panic (if the initrd is not set up) or stuck in the initrd "/init"
process, it is set up, however, if you do apply this patch, there should
not be problems with booting or seeing both contents of the drive. Tested
with the btrfs filesystem with a RAID configuration of having the root
drive '/' combined to make two 256GB Acer FA100 SSDs become 512GB in total
storage.
