From 35ffd08d9bc92b5d56f6536406c379d82a757e7a Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 7 Jul 2015 21:48:23 +0200 Subject: kconfig: Delete unnecessary checks before the function call "sym_calc_value" The sym_calc_value() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

COMMANDs and PARAMs are treated slightly different by the underlying parser. While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled characters") introduced a warning for unsupported characters around PARAMs, it does not cover situations where a COMMAND has additional characters before it. This change makes Kconfig emit a warning if superfluous characters are found before COMMANDs. As the 'help' statement sometimes is written as '---help---', the '-' character would now also be regarded as unhandled and generate a warning. To avoid that, '-' is added to the list of allowed characters, and the token '---help---' is included in the zconf.gperf file.

As I could not find out which flex/gperf version was used to generate the previous version, I used flex 2.5.35 and gperf 3.0.4 from Ubuntu 14.04 - this also leads to the big number of changed lines in this patch.
