Subject: [PATCH 05/14] isdn: isdnloop: suppress a gcc-7 warning
Date: Fri, 14 Jul 2017 11:25:17 +0200 [thread overview]
Message-ID: <20170714092540.1217397-6-arnd@arndb.de> (raw)
In-Reply-To: <20170714092540.1217397-1-arnd@arndb.de>
We test whether a bit is set in a mask here, which is correct
but gcc warns about it as it thinks it might be confusing:
drivers/isdn/isdnloop/isdnloop.c:412:37: error: ?: using integer constants in boolean context, the expression will always evaluate to 'true' [-Werror=int-in-bool-context]
This replaces the negation of an integer with an equivalent
comparison to zero, which gets rid of the warning.
