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

|
|
|
3a9b20b |
It masks (but not fixes) the bug described in the commit message
|
|
|
3a9b20b |
but introduces a regression (no console is selected by SPCR)
|
|
|
3a9b20b |
in regular (no 'console=ttyAMA') case.
|
|
|
3a9b20b |

s/||/&&/ would not fix the problem as the root cause was identified
|
|
|
3a9b20b |
incorrectly.
