Subject: [RESEND PATCH v2 2/2] kconfig: trivial - adjust comments in expr.c

From: Martin Walch <walch.martin@....de>

Replace any C99 comments with traditional ones (/*...*/).

Also fix the contents of two comments:

1) the second occurrence of
(a='b') && (a!='c') -> 'b'='c' ? 'n' : a='b'
is probably copy & paste from above, missing the adjustment corresponding
to the code.
It should probably read
(a!='b') && (a='c') -> 'b'='c' ? 'n' : a='c'

2) that one is similar:
(a!='m') && (a!='n') -> (a='m')
it should be
(a!='m') && (a!='n') -> (a='y')
