The original patch makes condition always true, so it is wrong.

This reverts commit aea9a80ba98a0c9b4de88850260e9fbdcc98360b.

It seems fairly clear that the intent of the code merely warrants
s/||/&&/ - wouldn't it be more straightforward to just fix that?

No, I don't think so.  The description of the patch says that it fixes a problem
of double printing the logs with SPCR and both console=ttyAMA and earlycon are specified
on the command string.  That wrong patch does "fix" it, but introduces
a regression with the regular case.

With s/||/&&/ it would not even 'fix' the described problem.

Thank you
