From mboxrd@z Thu Jan 1 00:00:00 1970 From: James Bottomley Subject: checkpatch: kill the bogus camelcase check Date: Tue, 09 Apr 2013 14:50:54 -0700 Message-ID: <1365544254.2946.53.camel@dabdike> Mime-Version: 1.0 Content-Type: text/plain; charset="ISO-8859-15" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Andy Whitcroft , Joe Perches Cc: linux-kernel , linux-scsi List-Id: linux-scsi@vger.kernel.org It's making checkpatch unusable on most drivers because it's spewing tons of bogus warnings. The problem is the assumption that studly caps is always wrong: it isn't if the variables are named after the various conventions in the hardware programming guides (which are usually written by Microsoft people). In order to encourage people to use checkpatch, it has to be *useful* it can't stray too far into dogmatic things like this that are essentially unfixable by most people who submit patches.
