Message-Id: <1356006355-6819-1-git-send-email-bp@alien8.de> Date: Thu, 20 Dec 2012 13:25:55 +0100 From: Borislav Petkov <bp@...en8.de> To: LKML <linux-kernel@...r.kernel.org> Cc: Borislav Petkov <bp@...en8.de>, Jeff Garzik <jgarzik@...ox.com>, linux-ide@...r.kernel.org Subject: [PATCH] libata: Shut up annoying native_sectors warning I'm getting this drivers/ata/libata-core.c: In function ‘ata_hpa_resize’: drivers/ata/libata-core.c:1397:3: warning: ‘native_sectors’ may be used uninitialized in this function [-Wmaybe-uninitialized] for a couple of kernel releases now with gcc (Debian 4.7.2-4) 4.7.2. And the warning is bogus because ata_read_native_max_address either returns a sensible max_sectors aka native_sectors through its second arg pointer or an error value which is properly handled in its caller ata_hpa_resize(). So shut up gcc already.
