No, the structure should be changed to actually be correct, as that is
not how it should be declared in order to not have any padding between
variables in the structure :)
But note, running checkpatch on code outside of drivers/staging/ is not
always welcome by some subsystem maintainers, so be careful about doing
lots of these types of changes in subsystems you do not have experience
contributing to.
good luck!
