Subject: [PATCH, RESEND 02/14] ata: avoid gcc-7 warning in ata_timing_quantize
Date: Fri, 14 Jul 2017 11:25:14 +0200 [thread overview]
Message-ID: <20170714092540.1217397-3-arnd@arndb.de> (raw)
In-Reply-To: <20170714092540.1217397-1-arnd@arndb.de>
gcc-7 warns about the result of a constant multiplication used as
a boolean:
drivers/ata/libata-core.c: In function 'ata_timing_quantize':
drivers/ata/libata-core.c:3164:30: warning: '*' in boolean context, suggest '&&' instead [-Wint-in-bool-context]
This slightly rearranges the macro to simplify the code and avoid
the warning at the same time.
