From 94d4350c544066d590eee93582220128e8be8b1c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 7 Oct 2010 09:42:43 -0300 Subject: [PATCH] [media] staging/tm6000: Fix a warning message MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit I added a code to the driver to force it to produce a warning. This were intended to remind me about a very bad hack. I never found a way to workaround. So, instead of those warnings: drivers/staging/tm6000/tm6000-core.c: In function ‘tm6000_init_analog_mode’: drivers/staging/tm6000/tm6000-core.c:328: warning: ISO C90 forbids mixed declarations and code Let's document the issue and hope if someone with the support of the vendor might fix it.
