From 2bf936290baff2507763a2540cd9029e70ae39e2 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 7 Dec 2011 07:48:16 -0200 Subject: [PATCH] [media] xc5000: Remove the global mutex lock at xc5000 firmware init As reported by Devin Heitmueller : > It seems like a change such as this could significantly change the > timing of tuner initialization if you have multiple xc5000 based > products that might have a slow i2c bus. Was that intentional? After discussed with Eddi de Pierri , it was pointed that the change was not intentional, and it was just a trial while developing the patches that add support for HVR-930C. So, remove this hack.
