[PATCH] of: correct of_console_check()'s return value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




The comments above of_console_check() say that it will return TRUE if it
registers a preferred console, but add_preferred_console() uses a
0-equals-success convention, so ths leaves of_console_check() with an
inconsistent policy for its return values.

Fortunately, nobody was actually checking the return value of
of_console_check(), so this isn't significant at the moment.

But let's match the comments, so we're doing what we say.

Fixes: 3482f2c52b77 ('of: Create of_console_check() for selecting a console specified in /chosen')

This is one way to fix it. Another possibility includes changing
of_console_check() to use 0-as-success
