On lkml suggestions were made to split up such trivial typo fixes into per subsystem
patches:
--- a/arch/x86/boot/compressed/eboot.c
+++ b/arch/x86/boot/compressed/eboot.c

This patch is the result of the following script:
$ sed -i 's/;;$/;/g' $(git grep -E ';;$' | grep "\.[ch]:" | grep -vwE 'for|ia64' | cut -d: -f1 | sort | uniq)
... followed by manual review to make sure it's all good.
Splitting this up is just crazy talk, let's get over with this and just do it.

Users who are booting off their Opal enabled drives are having
issues when they have a shadow MBR set up after s3/resume cycle.
When the Drive has a shadow MBR setup the MBRDone flag is set to
false upon power loss (S3/S4/S5). When the MBRDone flag is false
I/O to LBA 0 -> LBA_END_MBR are remapped to the shadow mbr
of the drive. If the drive contains useful data in the 0 -> end_mbr
range upon s3 resume the user can never get to that data as the
drive will keep remapping it to the MBR. To fix this when we unlock
on S3 resume, we need to tell the drive that we're done with the
shadow mbr (even though we didnt use it) by setting true to MBRDone.
This way the drive will stop the remapping and the user can access
their data.

During an error on a comannd, ex: user provides wrong pw to unlock
range, we will gracefully terminate the opal session. We want to
propagate the original error to userland instead of the result of
the session termination, which is almost always a success.

Before we free the opal structure we need to clean up any saved

By embedding the function data with the function sequence, we can
eliminate the external function data and state variable code. It also
made obvious some other small cleanups.

Insted of bloating the containing structure with it all the time this
allocates struct opal_dev dynamically. Additionally this allows moving
the definition of struct opal_dev into sed-opal.c. For this a new
private data field is added to it that is passed to the send/receive
callback. After that a lot of internals can be made private as well.

This patch set also enables logic to save a password to
